B is on line AC. If AC = 28, AB = x^2+2x, and BC = x, Find the value of x and AB

X = 4

Step-by-step explanation:

AB + BC = AC

x^2 +2x + x = 28

×^2 + 3× - 28 = 0

Step 1: Factor left side of equation.

(x−4)(x+7)=0

Step 2: Set factors equal to 0.

x−4=0 or x+7=0

x=4 or x=−7

x = 4 is the correct answer because the distance cant be negative

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
