Answer:

1 and 7

Step-by-step explanation:

(x+4)(x-2) = x²+2x-8

set up proportion:

2x-3/ x²+2x-8 = 1/5

cross-multiply:

5(2x-3) = x²+2x-8

10x-15 = x²+2x-8

Combine Like Terms:

x²-8x+7

Factor:

(x-7)(x-1)

set each factor equal to zero and solve:  x = 1, x = 7

Answer:

[tex] \frac{(2x - 3)}{(x + 4)(x - 2)} = \frac{1}{5} \\ \frac{2x - 3}{x {}^{2} - 2x + 4x - 8} = \frac{1}{5} \\ x {}^{2} - 2x + 4x - 8 = 5(2x - 3) \\ x {}^{2} + 2x - 8 = 10x - 15 \\ x {}^{2} + 2x - 10x = - 15 + 8 \\ x { }^{2} - 8x = - 7 \\ x {}^{2} - 8x + 7 = 0 \\ x {}^{2} - x - 7x + 7 = 0 \\ x(x - 1) + 7(x - 1) \\ x + 7 = 0 \\ x = - 7or \\ x - 1 = 0 \\ x = 1[/tex]

Answer:

Pyramid A is 10*10*8/3 which is 800/3 and Pyramid B is 15*15*12/3 which is 2700/3, so the ratio would simply be 8:27 uwu

Step-by-step explanation:

Answer:

36(x + 1)^2 = 0 or 36x^2 + 72x + 36

Step-by-step explanation:

s^2 = area of a square

(6x + 6) (6x + 6)

6x*6x = 36x^2

6x*6 = 36x

6*6x = 36x

6*6 = 36

36x^2 + 36x + 36x + 36

36x^2 + 72x + 36

36(x + 1)^2 = 0

Answer:

Thank to Goalscore24 correcting me, its actually Maria walking faster

Because 40 divided by 25 is 1.6

and 30 divided by 10 is 3

So Maria runs 3 miles in 1 second, and Luke runs 1.6 miles in 1 second

So Maria is faster.

Answer:

30%

Step-by-step explanation:

Given data

Area of Home= 2,200 square feet

Area of wood flooring=  660 square feet

The percent of wood flooring in the house can be gotten as

=660/2200*100

=0.3*100

= 30%

Hence the wooden floor occupies 30%.

Answer: UST = 77

Step-by-step explanation:

Angle RSU and angle UST together measure 180. (half of a circle) (or you can say they are a linear pair...either way they would sum to 180) 180-103 = 77

Answer:

Step-by-step explanation:

Remark

The formula you use is (Electricity / Total Income ) * 100

The ratio becomes 53.7/1725  * 100%

The ratio is 53.7/1725 * 100 = 0.03113 * 100

The % = 0.03113 * 100 = 3.113

To the closest tenth that is 3.1%

Answer:

They are 8 units apart, and the y-intercept of line A is above the x-axis by 6 units, and line B is below the x-axis by 2 units

Step-by-step explanation:

Remember your y-intercept has an x value of zero, so line B has a y intercept of (0,-2)

now let's find b in the original equation so

y - 8 = -2x - 2 so y = -2x -2 + 8, so y = -2x + 6

So line A has a y-intercept of (0,6)

They are 8 units apart, and the y-intercept of line A is above the x-axis by 6 units, and line B is below the x-axis by 2 units
