Ten and seventy-three hundredths
Answer:
B. 7x - 5
Explanation
Given the expression 21x^2 + 13x – 20, to get which of the given expression is a factor we will have to factorize the equation first as shown;
21x^2 + 13x – 20
= 21x^2 + 28x - 15x - 20
= 7x(3x+4) -5(3x+4)
= (7x-5)(3x+4)
Hence one of the factors is 7x - 5
Answer:
9 x 3 = 27, 27 x 2 = 54
4 x 3 = 12, 12 x 2 = 24
9 x 4 = 36, 36 x 2 = 72
Add given areas:
54 + 24 + 72 = 150 cm^2 is your answer.
