Look at it step by step guys:a\9=-4 so u just cross in top and bottom that will be -36=a ,or a=-36.....
Answer:
The answer is B
Step-by-step explanation:
S.A of pyramid = base area × 4(area of triangle)
base area = (24×24)in
= 576in²
area of triangle = (1/2)×24×12
= 144in²
S.A = 576 + 4(144)
= 1152in²
Answer:
Step-by-step explanation:
A = ½(5.5)(6.4) + ½(5.5)(5.2)
A = ½(5.5)(6.4 + 5.2)
A = ½(5.5)(11.6)
A = 31.9 in²
Apply the distributive property.
9(6 + 5x) - x(x - 1) =
54 + 45x + -x^2 + x =
54 + 46x + -x^2
So, 54 + 46x + -x^2 is the answer.
