Find the solution(s) for x in the equation below.
x^2+10x+21=0
Answer:
Hope this helps
Step-by-step explanation:
x= -3, -7
Answer:
x = -7, -3
Step-by-step explanation:
Try to factor the left side of the equation.
(x +7)(x + 3) = 0 Remember that if AB = 0, then A = 0 or B = 0 or both A and B = 0
Therefore, x + 7 = 0 or x + 3 = 0
x = -7 or x = -3
∆ ABC is isosceles with AB= AC= 7.5cm and BC= 0 cm .the height AD from A to BC, is 6cm . find the area of ∆ ABC what will be the height from C to AB i.e., CE
I have attached an image of the triangle.
BC = 9 cm
Answer:
CE = 7.2 cm
Step-by-step explanation:
In the attached triangle, we see that;
AB = AC = 7.5cm
BC = 9 cm
AD = 6cm
BC = 9cm
Formula for area of triangle is given as;
A = ½bh
Where b is base and h is height.
For the ∆ ABC with BC as base,
Area = ½ × 9 × 6 = 27 m²
Similarly, For ∆ ABC with AB as base,
Area = ½ × 7.5 × CE
Now, area from earlier is 27 cm²
Thus;
½ × 7.5 × CE = 27
Multiply both sides by 2 to get;
7.5CE = 54
CE = 54/7.5
CE = 7.2 cm

PLEASE HELP ME
given m||n, fine the value of x.
(X+12)° (4x-7)°
Answer:
35
Step-by-step explanation:
When the two lines being crossed are Parallel Lines the Consecutive Interior Angles add up to 180°.
So, x + 12 + 4x - 7 = 180.
5x + 5 = 180
5x = 175
x = 35
HELP ASAP AND PLEASE PUT THE STEPS
Answer:
hii
Step-by-step explanation:
interior corner of the triangle is 180°
180° - 78° - 90° = 12°
x = 12°
2y - 1 = 24
2y = 24 + 1
y = 25/2
y = 12.5
Using the expression 7x = 3y, ify is 35, what is x?
A. 35 B. 21 C. 15 D. 105
Answer:
c.15
Step-by-step explanation:
3*35= 105
since 7x=105 you divide 105 by 7 which is 15
Answer:
7x=3y
7x=3(35)
7x=105
x=105/7
x=15

Coordinates (2,5) (6,11) what's the equation of the line?
Answer:
y= 2x+1
Step-by-step explanation:
Using the general linear form y=mx+c
First find the gradient: change in y/change in x
11-5/6-2 = 6/3= 2
y=2x+c
Secondly find out c:
Use one of the coordinats
5= 2(2)+c
5=4+c
-4
1=c
y= 2x+1
5x + 1 = 56
Solving 2 step equations?
Answer:
the x would equal to 11 ,so x=11

Solve each equation or formula for the specified variable.
y= 1/4x -12,for x
Answer:
Step-by-step explanation:
Y = 1/4x - 12
Adding 12 on both sides
12y = 1/4x
12y/ 1/4 = x
3y = x

1) (-5) - 5
2) (-10) + 11
Answer:
1) -10
2) 1
Step-by-step explanation:
1) (-5) - 5
- Removing the brackets won't change anything since it is subtraction, so now it will be - 5-5 which is equal to -10.
-5 -5 = -10
2) (-10) + 11
- The same case applies here since it is addition.
-10 + 11 = 1
Answer:
1) -10
2) -1
Step-by-step explanation:
[tex]( - 5) - 5 = - 10 \\ \\ ( - 10) + 11 = - 1 \: [/tex]
Dan’s new appliance arrived in a cardboard box in the shape of cube. What is the surface area of the cardboard box?
A cube has side lengths of 3 feet.
Use the formula S A = 6 s squared, where SA is the surface area of the cube and s is the length of each side.
18 Feet squared
36 Feet squared
54 Feet squared
324 Feet squared
15 points please help
Answer:
36
Step-by-step explanation:
it says 6 with a 2 so u multiply 6 by 2 and get 12 then u multiply the 12 by the 3 and get 36 SO SRY IF IM WRONG !!
Answer:
Option (3)
Step-by-step explanation:
Formula to calculate the surface area of a cardboard box in the shape of a cube is,
Surface area = 6(Side)²
If the length of the each side of the box is = 3 feet
Surface area of the cube = 6(3)²
= 6 × 9
= 54 square feet
Therefore, Surface area of the box in the shape of a cube is 54 square feet.
Option (3) is the correct option.
If a town with a population of 500 doubles in size every 80 years, what will the population be 160 years from now?
Answer: 2000
Step-by-step explanation:
From the information, we are informed that a population of 500 doubles in size every 80 years. Therefore, the population in 160 years will have doubled twice i.e 160/80 = 2 times
First time doubling = 500 × 2 = 1000
Second time doubling = 1000 × 2 = 2000

Answer:
Step-by-step explanation:
3y = -x + 6
y = -1/3x + 2
y - 3 = -1/3(x + 1)
y - 3 = -1/3x - 1/3
y - 9/3 = -1/3x - 1/3
y = -1/3x + 8/3

Milan bought a table for Rs 3600. He sells it to Kirtim at a profit of Rs 205. Kritim sells it at
Rs 4968 to Aayush. Find the percentage profit of Kritim.
Answer:
23.41%
Step-by-step explanation:
Kirtim's purchase price was 3600 + 205 = 3805,
Kirtim sold the table for 4968 for a profit of 4968 - 3805 = 1163
Assuming requirement is for profit on revenue, so
P = 100 * (1163/4968) = 23.41%

How many multiples of 5 are there in between 100 and 300?
Answer:
39 multiplesStep-by-step explanation:
Consider AP:
105, 110, ..., 295As multiples of 5 between 100 and 300
The first term is 105, the common difference is 5, the last term is 295.
Use the nth term formula:
105 + 5(n - 1) = 2955(n - 1) = 190n - 1 = 190/5n - 1 = 38n = 39Answer:
Solution given:
first term [a]=100
last term[l]=300
common difference [d]=5
second term[b]=100+5=105
now
we have
l=a+(n-1)d
substituting value
300=100+(n-1)5
300-100=(n-1)5
200/5=n-1
40=n-1
n=40+1
there are 41 multiple in between 100 and 300/including it but no including its 41-2=39 multiple

Madison saves 40% of all that she earns for washing cars. So far she has saved $72. How much has she earned in all?
Answer:
Madison has earned 180 dollars in all.
Step-by-step explanation:
Let [tex]x[/tex] denotes amount earned by Madison.
Percentage of amount saved by Madison [tex]=\frac{40}{100} x[/tex]
Amount saved by Madison [tex]=72[/tex] dollars
Therefore,
[tex]\frac{40}{100}x=72\\x=72(\frac{100}{40})[/tex]
[tex]=180[/tex] dollars
So,
Madison has earned 180 dollars in all.
