X^2 - 16x + 64 = 
(x - 8)(x - 8) =
(x - 8)^2

 ** see ur x term (-16x)....u take half of ur x term, which would be -8, then square it...(-8)^2 = 64...then add that to both sides. Then factor it.

Answer:

What do you want your answer in? Exact or decimal form?

Exact form: 212/3

Decimal form 70.6

Step-by-step explanation:

Cancel the common factor of 8 and 6 for 53 * 4/3. Multiply 53(4/3), 212/3. This would be the answer for the exact form, decimal form is created by dividing 212 by 3, for 70.66666--.

Give one combination of two factors whose product is 0.24, if one of the factors is a whole number greater than 1.
Nutka1998 [239]
0.24 is an even number....so 2 will be a factor

2x = 0.24
x = 0.24 / 2
x = 0.12

so 2 factors would be 2 and 0.12.....because 2 * 0.12 = 0.24

A right triangular prism is shown.What is the lateral surface area?
makkiz [27]

The general formula for the lateral surface area of a right prism is

L = ph

where p represents the perimeter of the base and h represents the height of the prism.

In our case, the perimeter is the sum of the bases.

p = 5 + 5.6 + 2.5 = 13.1 cm

now, the height of the prism is 8 cm

then L = 13.1 cm x 8 cm = 104.8cm^2
