Answer:
517.5 mi^2
Step-by-step explanation:
Divide shapes into 3 shapes ( 1 triangle and 2 rectangles
b = 17
h = 25
Area of triangle = Bh
A = (17)(25)
A = 212.5 mi^2
Area of 1st rectangle = lw = 17(9) = 153 mi^2
Area of 2nd rectangle = lw = 19(8) = 152 mi^2
Area of figure = 212.5 +153 + 152 = 517.5 mi^2
Pentagons have five sides, so 5*7 is 35 units
Here, we are required to determine which expression shows the sum of 72 and 96 as the product of the GCF and a sum of two numbers with no common factor?
The answer is Choice B: 24(3 + 4)
Factors of 72 are;
2 × 2 × 2 × 3 × 3
Factors of 96 are;
2 × 2 × 2 × 2 × 2 × 3
The factors in bold above are common to 72 and 96 and therefore gives a total of 24 which is the GCF of 72 and 96.
The remaining factor of 72 and 96 are 3 and 4 respectively.
And, since 3 and 4 have no common factor,
Therefore, the expression which shows the sum of 72 and 96 as the product of the GCF
and a sum of two numbers with no common factor is:
24(3 + 4)
