answer:
area: 40cm²
perimeter = 26cm
step-by-step explanation:
- i do not know which one this is telling you to find so i put both area and perimeter
area:
- know the formula
- formula = l x w
- l = length
- w = width
- plug in what you have
l x w
5 x 8
= 40cm²
perimeter:
- for this you just have to each side
- since this is rectangle opposite sides are equal
5 + 5 + 8 + 8
= 26cm
We know that V= 4/3 pi r^3
So r^3= 140/ ((4/3) pi)= 33.422538
Hence r= 3.221166
SA = 4 pi r^2
= 4 pi 3.221166^2
= 130.39 cm^2
= 130 cm^2
Answer:
B. x(x) + (−6)(−3)
NOT equivalent to (x − 6)(x − 3)
Step-by-step explanation:
(x − 6)(x − 3)
= x^2 - 3x - 6x + 18
= x^2 - 9x + 18
A. (6 − x)(3 − x)
= 18 - 6x - 3x + x^2
= 18 - 9x + x^2
= x^2 - 9x + 18 ---->equivalent to (x − 6)(x − 3)
B. x(x) + (−6)(−3) = x^2 + 18 ----> NOT equivalent to (x − 6)(x − 3)
C. x2 − 3x − 6x + 18 = x^2 - 9x + 18 --> equivalent to (x − 6)(x − 3)
D. x(x − 6) − 3(x − 6)
= x^2 - 6x - 3x + 18
= x^2 - 9x + 18 ---->equivalent to (x − 6)(x − 3)
b= 1/2
