Simplify the answer

Andru [333]

Answer:

- 20 + 8i

Step-by-step explanation:

Noting that i² = - 1

Given

[(6i + 9) + (4i - 5)] × 2i ← evaluate the terms inside the square bracket

= ( 6i + 9 + 4i - 5 ) × 2i

= (10i + 4) × 2i ← multiply each term in the parenthesis by 2i

= 20i² + 8i

= 20(- 1) + 8i

= - 20 + 8i

Yuliya22 [10]

Answer:

87.92 cubic inches

to find the volume of a cylinder the formula is V = $\pi$ $r^{2}$ h

so first i squared 2

2x2= 4

i then multiplied 4 by the height (7)

4x7 = 28

then times 28 by pi (3.14)

28x 3.14 = 87.92

pantera1 [17]

Answer:

$6x^2$

Step-by-step explanation:

Express as product of prime factors.

$30x^2=2\times 3\times 5\times x^2$

$66x^5=2\times 3\times 11\times x^5$

The greatest common factor is the product of the least powers of the common factors.

The GCF is

$2\times 3\times x^2=6x^2$
