Hi there

Root=0.5 means x=0.5

Plug in 0.5 for x
(b-5)0.5^2-(b-2)0.5+b=0
(b-5)0.25-(b-2)035+b=0
Simplify
0.75b-2.25=0
b=3

Hope this helps

Neeta is a fourth grader. She is 4 feet 7 inches tall. When she was bom she was 17 inches long. How much has Neeta grown since s

Virty [35]

Answer:

Step-by-step explanation:

First, find Neeta's total height in inches:

4 feet in inches is 4*12, which equals 48

Add the other 7 inches of her height to get 55 inches.

Then, subtract her initial height from her current height.

55 - 17 = 38. That is how many inches she has grown. Convert that to feet by dividing 38 by 12.

You get about 3.16, which is over 3 feet. So A is the correct answer.

A landscaper has enough cement to make a patio with an area of 150 Sq ft. The homeowner wants the length of the patio to be 6 ft

Natasha_Volkova [10]

$A=lw=150\\l=w+6\\(w+6)w=150\\w^2+6w=150\\w^2+6w-150=0\\w=\frac{-b+-\sqrt{b^2-4ac}}{2a}\\w=\frac{-(6)+-\sqrt{(6)^2-4(1)(-150)}}{2(1)}\\w=\frac{-6+-\sqrt{36+600}}{2}\\w=\frac{-6+-\sqrt{636}}{2}\\w=\frac{-6+-2\sqrt{159}}{2}\\w=-3+-\sqrt{159}>0\\w=-3+\sqrt{159}\\\\l=(-3+\sqrt{159})+6\\l=3+\sqrt{159}$

Width = -3 + sqrt(159)
Length = 3 + sqrt(159)

Find x so that x, X +2, X'+3 are the first three terms of a geometric sequence. Then find the 5" term of the

velikii [3]

Answer:

The fifth term is -1/4.

Step-by-step explanation:

We know that the first three terms of the geometric sequence is x, x + 2, and x + 3.

So, our first term is x.

Then our second term will be our first term multiplied by the common ratio r. So:

$x+2=xr$
