Divide the pentagon into a triangle and rectangle.
Rectangle: 12in*6in=72in^2
Triangle: (12in*5in)/2=30in^2
72in^2+30in^2=102in^2
Answer:
x = - 7, x = - 1
Step-by-step explanation:
To find the zeros let f(x) = 0 , that is
x² + 8x + 7 = 0
Consider the factors of the constant term (+ 7) which sum to give the coefficient of the x- term (+ 8)
The factors are + 7 and + 1 , since
7 × 1 = + 7 and 7 + 1 = + 8 , then
x² + 8x + 7 = 0
(x + 7)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x + 1 = 0 ⇒ x = - 1

just got the answer on edge,
edge is the stupidest waste of time I've ever used, gotta get them credits to graduate though.
Did you say he can choose " 1 snack " ?
Well then. There are 9 different items in the box, so he has
9 different choices of snack.
I guess that means he can choose his snack in 9 ways.
Answer: 42 1/2
Step-by-step explanation:
We subtract 26 1/6 from 68 1/2. We do this by finding the LCM of 6 and 2. That is 6. We multiply 1/2 by 3/3 to get 3/6. Now, we subtract. 68 - 26 is 42, and 3/6 - 1/6 is 2/6. Our answer is 42 2/6. That can be simplified to 42 1/3.
