P=2L+2W
P=2*20+2*15= 40+30=70 in
A=W*L=20*15=300 in²

Step-by-step explanation:
Answer:
x = -25/12 or x = -0.2
Step-by-step explanation:
x(x+5)+6(x+5)=(x+5)
Distribute
x^2 + 5x + 6x + 30 = x + 5
Combine
x^2 + 11x + 30 = x + 5
Subtract 1x from both sides
x^2 + 10x + 30 = 5
Subtract 30 from both sides
12x = -25
Divide 12 on both sides
x = -25/12 or -0.2
Answer:
A and E.
Step-by-step explanation:
Using the math from 7th grade, 6 rooted is 36/9=4+10 is 14. Everything else you must multiply everything in parenthesis, by the outside number, then you add them. E is right because -15+35=20-6=14. Yw.
