Help me ASAP‼️! A walkway surrounds a rectangular garden. The width of the garden is 9 feet, and the length is 12 feet. The width of the walkway around the garden is the same on every side . Write an expression that represents the total area of the garden and walkway.
_____ q^2+____q+_____
Answer:
total area of the garden and walkway = 2a² + 21a + 54
Step-by-step explanation:
The walkway surrounds the rectangular garden. The width of the garden is 9 ft and the length is 12 ft. Since the width of the walkway around the garden is the same on every side let us use a to represent the width around the garden.
The garden is rectangular and the width of the walkway around the garden is uniform. The width added on both end of the width of the rectangle will be 2a while the width added to the both length of the rectangle will be 2a also.
Therefore
total area of the garden and walkway = length × width
length of garden and the walkway = 2a + 12
width of garden and the walkway = 2a + 9
total area of the garden and walkway = (2a + 12)(2a + 9)
total area of the garden and walkway = 4a² + 18a + 24a + 108
total area of the garden and walkway = 4a² + 42a + 108
divide through by 2
total area of the garden and walkway = 2a² + 21a + 54

Answer:
One kilogram of oranges cost $3.Step-by-step explanation:
The problem states
1 kilogram of bananas costs as much as 2 kilograms of oranges. ([tex]1 \ kg \ bananas = 2 \ kg \ oranges[/tex])30 kilograms of oranges plues 45 kilograms of bananas cost $360.Let's call [tex]x[/tex] one kilogram bananas and [tex]y[/tex] one kilogram oranges. The cost is related by
[tex]x=2y[/tex]
Also, we know by given
[tex]45x+30y=360[/tex]
Replacing the first equation into the second one, we have
[tex]45(2y)+30y=360\\90y+30y=360\\120y=360\\y=\frac{360}{120}\\ y=3[/tex]
Then, we find the other value
[tex]x=2(3)=6[/tex]
Therefore, one kilogram of oranges cost $3.

Find the value of s.
s+ 14 = 26
Answer:
12
Step-by-step explanation:
1. Write out s+14=26
2. Subtract 14 by both sides to isolate s.
3. s = 12
Answer:
s = 12
Step-by-step explanation:
s + 14 = 26
- 14 - 14 Subtract 14 from both sides
s = 12
Plug this back into the equation to make sure it works
12 + 14 = 26 Add
26 = 26 This solution does work

A.(- 20, - 3)
B.(- 10, - 3)
C.(- 3, - 10)
D.(- 3, - 20)
Answer:
C. (-3, -10)
Step-by-step explanation:
First label the 2 equations.
y=5x +5 -----(1)
x= -3 -----(2)
subst. (2) into (1):
y= 5(-3) +5
y= -15 +5 (expand)
y= -10 (simplify)
Thus, the answer is (-3, -10).
Answer:
THe answer is C
Step-by-step explanation:A
As seen by the last answer when we substitute the variable we can get (-3,-10)
x=-3------(2)
y=5x+5-----(1)
y=5(-3)+5
y=-15+5
y=-10

a) List all the possible types of sandwiches Hugo could make.
One has been done for you (write all your answers on one line).
WCM,
b) What fraction of the possible types of sandwich have Turkey and Ketchup?
Answer:
a) WCK, WTM, WTK, BCM, BCK, BTM, BTK.
b) 1/4
Step-by-step explanation:
a)
For this answer we just need to write all possibilities of sandwiches, so we can use the options given to create all the sandwiches, besides the one given:
(WCM given), WCK, WTM, WTK, BCM, BCK, BTM, BTK.
b)
From the letter a), we have 8 possible options. From these options, we have 2 that have turkey and ketchup (WTK and BTK), so the probability is the number of options we want over the total number of options:

Holly finds that (11m – 13n + 6mn) – (10m – 7n + 3mn) = m – 20n + 9mn. What error did Holly make?
Answer: A ) She only used the additive inverse of 10m when combining like terms .
Step-by-step explanation:
Holly only used the additive inverse of 10m when combining like terms. The equality is erroneous because the equation was evaluated well. The calculations should be as follows:
11m -13n + 6mn - 10m + 7n - 3mn = 1m - 6n +3mn
She should have subtracted 13n and 7n then take the negative value. Also, subtract 6mn and 3mn.

In triangle ABC angle A=45 angle B =40 and a=7.Which equation should you solve to find b?
Answer:
Sin45 / 7 = sin40 / b
We have been given that in triangle ABC angle A=45 angle B =40 and a=7. We are asked to find the equation that we can use to solve for 'f'.
We have two angles and opposite sides to these angles.
We will use Law of Sines to solve our given problem.
[tex]\frac{a}{\sin(A)}=\frac{b}{\sin(B)}=\frac{c}{\sin(C)}[/tex], where a, b and c are opposite sides corresponding to angles A, B, and C respectively.
The angle opposite to side b is 40 degrees and angle opposite to side a is 45 degrees.
Upon substituting these values in Law of Sines, we will get:
[tex]\frac{7}{\sin(45^{\circ})}=\frac{b}{\sin(40^{\circ})}[/tex]
Therefore, our required equation would be [tex]\frac{7}{\sin(45^{\circ})}=\frac{b}{\sin(40^{\circ})}[/tex].

Mr. Gilmore sells furniture. He earned $210 for selling 3 sofas. Mr. Gilmore
earned $570 for selling ll sofas. Which of the following equations represents this
situation, where s represents the number of sofas Mr. Gilmore sold and e
represents the amount he earned?
Let s represent the number of sofas and e represent the amount earned.
We have been given that Mr. Gilmore sells furniture. He earned $210 for selling 3 sofas. Mr. Gilmore earned $570 for selling 11 sofas. We are asked to write the equation for given scenario.
We have two points on a line that are (3,210) and (11,570).
Let us find slope of line passing through these points.
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{570-210}{11-3}[/tex]
[tex]m=\frac{360}{8}[/tex]
[tex]m=45[/tex]
Now we will use point-slope form of equation.
[tex]y-y_1=m(x-x_1)[/tex], where
m = Slope,
[tex](x_1,y_1)[/tex] = Any point on line.
[tex]y-210=45(x-3)[/tex]
[tex]y-210=45x-135[/tex]
[tex]y-210+210=45x-135+210[/tex]
[tex]y=45x+75[/tex]
Since amount earned is e and number of sofas is s, so our equation would be [tex]e=45s+75[/tex].
Therefore, our required equation would be [tex]e=45s+75[/tex].

Step-by-step explanation:
14) 1/((1/4) + (1/7)) = 1/(11/28) = 28/11 (C)
15) 1/((1/x) + (1/3x)) = 3--> (1/x) + (1/3x) = 1/3 --> 4/3x = 1/3 --> x = 4 (D)
16) 56 - 28 = 28 --> 28/(4*2) = 3.5 hours --> 56/3.5 = 16mph (when adding the stream's speed)--> 16mph - 4mph = 12mph (B)
17) 540 - 480 = 60 --> 60/(9*2) = 10/3 hours --> 540/(10/3) = 162 (when adding the current) --> 162mph - 9mph = 153mph (B)

Answer:

Step-by-step explanation:
So, y = 1/2x - 2 is only graphed in A and D.
And x ≤ 6 is only graphed in graph A.
The graph of the piecewise function is the first graph (counting from the top).
Which is the graph of the function?
Here we have a piecewise function:
f(x) = 0.5*x - 2 if x ≤ 6
f(x) = -x - 1 if x > 6
So, we have an increasing line for x smaller or equal than 6, and a decreasing line for x > 6. Such that we should to have a closed dot at the end of the increasing line, because in that part we have the symbol ≥, meaning that x = 6 belongs to that part.
Then the correct graph is the first option.
