Problem 13
10p+10q factors to 10(p+q). If we apply the distributive property, we can distribute the 10 to each term inside (p and q) to get
10(p+q) = (10 times p)+(10 times q) = 10*p + 10*q = 10p+10q
so we get the original expression again. Here 10 is the GCF of the two terms.
--------------------------------------------------------------
Plug p = 1 and q = 2 into the factored form
10*(p+q) = 10*(1+2) = 10*(3) = 30
As a check, let's plug those p,q values into the original expression
10*p+10*q = 10*1+10*2 = 10+20 = 30
We get the same output of 30

(9x³ + 5x) - (7x³ - 3x)
<u>Step 2: Solve</u>
- Distribute negative: 9x³ + 5x - 7x³ + 3x
- Combine like terms: 2x³ + 8x
Answer:
80
step by step explanation:
when a number is decreased by 19 %, u calculate backwards, making the % to 119% of 66. Hence it becomes 78.54 to be exact, but in the nearest tenth, it becomes 80.
