P = √ab
p² = ab
p²/b = a
a = p²/b
Step-by-step explanation:
the area of a triangle is
baseline × height / 2
we have here 2 triangles : the larger, outer shaded one, and the smaller, inner white one.
to get the area of the shaded part, we need to calculate the area of the large triangle and subtract the area of the smaller triangle.
large area :
12 × 15 / 2 = 6 × 15 = 90 ft²
small area :
8 × 10 / 2 = 4 × 10 = 40 ft²
the shaded area is
90 - 40 = 50 ft²
Answer:
b
Step-by-step explanation:
you can use trial and error to solve this btw that's what I used and once I got to answer choice b, i plugged in the 2 numbers into the equation based of of their axis once i did that the equation now looked like this 9=3+3, when you solve this the equation would then look like this 9=6 and we both know that 9 doesn't not equal 6 so that is your answer.
