a + 7a+3ab-2ab-1+6 Simplify
Answer:
8a + ab + 5
Step-by-step explanation:
1. a + 7a+3ab-2ab-1+6
2. combine like terms
(a + 7a) + (3ab - 2ab) + (-1+6)
8a + ab + 5
Answer:
8a + ab + 5
Step-by-step explanation:
combine like terms. like term have same variables
a and 7a ; 3ab and (-2ab) ; (-1) and 6 are like terms
a + 7a + 3ab - 2ab - 1 + 6 = 8a + ab + 5

Answer:
3, 1, - 1, - 3 and - 15
Step-by-step explanation:
To find the first 4 terms substitute n = 1, 2, 3, 4 into the rule, that is
a₁ = 5 - 2(1) = 5 - 2 = 3
a₂ = 5 - 2(2) = 5 - 4 = 1
a₃ = 5 - 2(3) = 5 - 6 = - 1
a₄ = 5 - 2(4) = 5 - 8 = - 3
The first 4 terms are 3, 1, - 1, - 3
For 10th term substitute n = 10 into the rule
a₁₀ = 5 - 2(10) = 5 - 20 = - 15

Multiply using FOIL or Table method (x + 4) (x + 5)
Answer:
[tex] {x}^{2} + 9x + 20[/tex]
Step-by-step explanation:
1) Use FOIL method: (a + b) (c + d) = ac + ad + bc + bd.
[tex] {x}^{2} + 5x + 4x + 20[/tex]
2) Collect like terms.
[tex] {x}^{2} + (5x + 4x) + 20[/tex]
3) Simplify.
[tex] {x}^{2} + 9x + 20[/tex]
Therefor, the answer is x² + 9x + 20.
What is the inverse of H(x)=1/2x+3
Answer:
x=-6
Step-by-step explanation:
Answer:
[tex]h^{-1}[/tex] (x) = 2x - 6
Step-by-step explanation:
let y = h(x) and rearrange making x the subject
y = [tex]\frac{1}{2}[/tex] x + 3 ( multiply through by 2 to clear the fraction )
2y = x + 6 ( subtract 6 from both sides )
2y - 6 = x
Change y back into terms of x with x = [tex]h^{-1}[/tex] (x)
[tex]h^{-1}[/tex] (x) = 2x - 6
Mr. Jamison wants to borrow $375,000 to
open a Pizza Shack franchise. If he can
pay $28,125 a year in interest, what
interest rate can he afford to pay on his
| loan? (Write your answer as a percent.)
Answer: The interest rate can he afford to pay on his | loan =7.5%
Step-by-step explanation:
Given: Principal amount = 375,000
Interest amount per year = $28,125
Interest percentage = [tex]\dfrac{\text{Interest}}{\text{Principal}}\times100\%[/tex]
[tex]=\dfrac{28125}{375000}\times100\%\\\\=7.5\%[/tex]
Hence, The interest rate can he afford to pay on his | loan =7.5%

Answer:
z = 65
Step-by-step explanation:
z + 81 + 34 = 180 (Sum of angles in a triangle is 180)
z + 115 = 180
z = 180 - 115
z = 65

How do I solve these questions and can I have one of the answers
Answer:
ok-
first thing to do is break the shapes into regular shapes that you already know how to figure the area of. so, #1 and #2 become an upright rectangle with a square attached to the bottom. #? is a rectangle with a semicircle at each end. #5 is a rectangle with a triangle up top... etc.
then, you figure the area of each part and add them all together.
let's look at #1:
right away, I see a square sticking off the right side that is 20x20- so that part is 400sq inches
then, I see the remainder as a rectangle that is 23x22.
23x22=506sq inches
then, add the 2 parts together.
506+400= 906sq inches total.
hope that helps!
Add.
(a2+6)+(4a+6)
What is the answer?
Look at the explanation to understand the answer.
Step-by-step explanation:
Step 1.
Rewrite (a2) in a2 + 6 so the a is before 2
(a2 + 6) + (4a + 6) ⇒ (2a + 6) + (4a + 6)
Step 2.
We'll need to organize 2a + 6 + 4a + 6 into groups of like terms, so we can combine them easier.
They're two groups of like terms in the expression.
First group: 2a and 4a
Second group: 6 and 6
Now, rewrite it so the 6 is added by the other 6.
2a + 4a + 6 + 6
Step 3.
We'll need to combine like terms in 2a + 4a + 6 + 6 by adding all the numerical coefficients and copying the literal parts, if any. No numerical coefficient implies value of 1. Numerical 'like' terms will be added.
We already know the groups with like terms.
First group: 2a and 4a
Second group: 6 and 6
Let's solve.
2a + 4a = 6a
6 + 6 = 12
Combine 6a and 12 up and you'll get your answer.
6a + 12 is the answer.

Maggie draws a triangle with a right angle. The other two angles have equal measures. What are the possible values of the exterior angles for Maggie's triangle? Explain.
Answer:
135°, 135° and 90°
Step-by-step explanation:
It is given a triangle with a right angle (90°) and the other two angles have equal measures, so they are both (45°)
exterior angles are thus 180 - 45, 180 - 45, 180 - 90
which are 135°, 135° and 90°.
Find the area of the triangle below.

Julie made five loaves of bread that had 1/4 cup of flour in each loaf. How many cups of flour were used in all?
Answer:
1 1/4 cups in total
Step-by-step explanation:
1 loaf-1/4 cup
2 loaf- 2/4 cup
3 loaf= 3/4 cup
4 loaf=4/4 cup
5 loafs in total equal: 1 1/4
Hope this helped!
Answer:
1 cup and 1/4
Step-by-step explanation:
one piece of bread is a quarter of a cup
and 4 quarters make a whole so- 4 loaves is one cup. then one loaf is equal to 1/4 so
4 and 1/4 cups
