Answer:
J 56
Step-by-step explanation:
The area of the figure is the large square x^2 minus the small square y^2
The area is x^2 -y^2 = 52
Since x and y are integers the of the squares must be 52
x^2 = y^2 +52
We know that it must be fairly large
Let y = 12
x^2 = 12^2 +52
x^2 = 144+52
x^2 = 196
x=14
The perimeter is the sum of the 4 sides
P = x+x + (x-y) +y+y + (x-y)
Combining like terms
P = 4x
P = 4(14)
P = 56
Answer:
I think its -10 or -8
Step-by-step explanation:
Answer:
β = 140 - α
we know that the "missing" angle is 40° since 40 + 140 = 180
we also know that the total sum of angles in a triangle is 180
so β = 180 - 40 - α
or β = 140 - α
Step-by-step explanation:
Answer:
x - 6
Step-by-step explanation:
A = L x W
A / L = W
x^2-11x+30 / x -5 = W (Simplify the numerator)
(x - 6) x ( x - 5) / x - 5 = W (Cancel the similar ones which is (x - 5) )
x - 6 = W
Hope that helps
Answer:
It could be both 2 positives, or 2 negatives.
Step-by-step explanation:
This is because a negative times a negative is a positive, and a positive times a positive is a positive.
