1 answer:
AfilCa [17]3 years ago
5 0

Answer:

D. 5

E. 7

Step-by-step explanation:

X^2-6x+40=6x+5

Bring all the terms to one side

Subtract 6x from each side

X^2-6x-6x+40=6x-6x+5

x^2 -12x+40 = 5

Subtract 5 from each side

x^2 -12x+40-5 = 5-5

x^2 -12x+35 =0

Factor

(x-5) (x-7)=0

Using the zero product property

x-5=0   x-7=0

x=5  x=7

Alena is packing a box that has a height of one inch more than the width and a length of three inches more than the width, as sh
Citrus2011 [14]

Answer:

The polynomial that represent the volume of the box is V=(x^{3}+4x^{2}+3x)\ in^{3}

Step-by-step explanation:

we know that

The volume of the box is equal to

V=LWH

we have

L=(x+3)\ in

W=x\ in

H=(x+1)\ in

substitute in the formula

V=(x+3)(x)(x+1)\\V=(x^{2} +3x)(x+1)\\V=x^{3}+x^{2} +3x^{2} +3x\\ V=(x^{3}+4x^{2}+3x)\ in^{3}

PLEASE HELP! No phony answers, thanks! Happy holidays, Merry Christmas!!
larisa [96]

Step-by-step explanation:

(f+g)(x) means we just add the 2 functions, so we have

(x-3) + 2x² = 2x² + x - 3

(f-g)(x) means we subtract g(x) from f(x), so we have

(x-3) - (2x²) = -2x²+x-3

Assuming that the dot signifies a multiplication sign and not a composition  sign, we have

(f*g)(x) = f(x) * g(x)

= (x-3) * 2x²

= 2x³ - 6x²

Plugging -2 in, we get

2(-2)³-6(-2)² = -16 -24 = -40

After a thorough research, there exists the same question that has the following choices.

A. 6.29 
<span>B. 12.57
</span><span>C. 18.86
</span><span>D. 25.13</span>

The correct answer is letter B 12. 57
First, we need to get the circumference
C = 2*pi*r
C = 12 pi
360/ 60+60 = 360/120 = 3
12 pi / 3 = 4 pi = 4 x 3.1415 = 12.57
