Answer:
a=8
Step-by-step explanation:
If we're using the distributive property, we should first open parentheses by multiplying -5*a and -5*3
-5*a= -5a
-5*3= -15
Now, we have the equation: -5a-15= -55
Add fifteen to both side:
-5a= -40
a=8
Answer:
a = 8
Step-by-step explanation:
-5(a + 3) = - 55
- 5a - 15 = - 55
55 - 15 = 5a
5a = 40
a = 40 : 5
a = 8

You have to add 25 for each one so you get the answer
P=2*(l+w)
p=2l+2w
2w=p - 2l
w= (p-2l)/2
