Answer:

12.50/100 X 110 = 13.75

13.75-12.50 = 1.25

12.50/100 X 109 = 13.625

13.625 + 1.25 = 14.875

Point M is the midpoint of segment AB.<br> AM=3x+40 and MB=x^2. Find x and AB

Nina [5.8K]

$\text{Hello there! :)}$

$x = 8\\\\AB = 128 \text{ units}$

-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

$\text{Since Point M is the midpoint of AB, then:}\\\\AM = MB\\\\$

$\text{Set the two equations equal to each other:}\\\\3x + 40 = x^{2} \\\\$

$\text{Move all terms over to one side to simplify more easily:}\\\\0 = x^{2} - 3x - 40$

$\text{Factor by finding numbers that sum up to -3 and multiply into -40:}\\\\0 = (x - 8)(x + 5)\\\\x = -5, 8$

$\text{The length of a segment cannot be negative, so choose the positive solution:}\\\\x = 8$

$\text{Substitute in this value of x into either AM or MB to solve for AB:}$

$AB = 2(MB)\\\\AB = 2(x^{2} )\\\\AB = 2(8^{2})\\ \\AB = 2(64)\\\\AB = 128 \text{ units}$

Answer:

Answer:C = 8

Answer:C = 8Step-by-step explanation:

-2(4c+16)^1/4+2=-2

Move the constant to the right and change the sign

-2(4c+16)^1/4= -2-2

transform expression

$- 2 \sqrt[4]{4c - 16} = - 4$

Divide each side by -2

$\sqrt[4]{4c - 16 } = 2$

raise both side of the equation by power of 4

4c-16=16

move constant to the right and change the sign

4c=16+16

4c=32

THEN DIVIDE BOTH SIDES BY 4

C = 8
