Answer:
area of 3rd figure is 20ft^2
and perimeter is 20 ft
Answer:
B
Step-by-step explanation:
Given
P = 2(l + b) ← distribute
P = 2l + 2b ( subtract 2b from both sides )
P - 2b = 2l ( divide both sides by 2 )
= l → B
-14x + 7x^2 is the answer
Answer:
1, 4, & 6
Step-by-step explanation:

Answer:
58
Step-by-step explanation:
Since two of the sides are both 6.2, we know that this is an isosceles triangle. Thus, the two angles opposite of x are both equal (61 degrees).
The angles inside of a triangle always add up to 180, so now we have
180 = 61 + 61 + x
Solving for x, we get x = 180 - (61 + 61) = 180 - 122 = 58
