Answer:
A) 
Step-by-step explanation:
The polynomial factored is equal to the area of the algebra tiles. This means the quadratic is

After writing out each tile as a term, combine like terms to simplify. This ia the quadratic.
Answer:
Step-by-step explanation:
10, 24 and 38 are composite numbers.
(10 can be divided by 5 and 2; 24 can be divided by 8, 3, 12 and 2; 38 can be divided by 19 and 2).
The others are prime numbers.
Answer:
1222
Step-by-step explanation:
312/12 = 26
So, you have to multiply y (47) by 26
This will get you 1222
Step-by-step explanation:
DE = 5x-2
DF = 3(x+3)
3(x+3) = 3 + 5x-2
3x+9= 5x+1
2x=8
x=4
DE=5×4-2=18
DE=18
Answer:
see below
Step-by-step explanation:
8- 2x - 5- 13x = 6
Combine like terms
-15x+3=6
Subtract 3 from each side
-15x+3-3=6-3
-15x = 3
Divide each side by -15
x = 3/-15
x = -1/5
Check
8 - 2(-1/5) -5 -13(-1/5) = 6
8 + 2/5 -5 +13/5 = 6
3 + 15/5 = 6
3+3=6
6=6
