Answer:
x = -4
Step-by-step explanation:
2x+4(2x+7)=3(2x+4)
Distribute
2x+8x + 28 = 6x +12
Combine like terms
10x +28 = 6x +12
Subtract 6x from each side
10-6x+28 = 6x +12 -6x
4x +28 = 12
Subtract 28 from each side
4x+28-28 = 12-28
4x = -16
Divide each side by 4
4x/4 = -16/4
x = -4
The answer is c and e. To find the zeros of a function and they give you options like this, just plug them into the equation until they equal 0.
1) A, 1:2
Because the ratio of the points is 7:14
2) C, 3:5
Because there are 9:15 boys, so divide by 3
3) C, 33 yards
Convert 1200 inches into yards, it makes 33.3
The first answer (question 4) is 12 and the second answer (question 5) is 13 hope this helps!!!
