Three times the sum of a number and seven is two less than five times the number. . a. 3x+7=5x-2. b. 3(x+7)=5x-2. c. 3(x+7)=2-5x

Nuetrik [128]

<span>We dissect each statement from the problem above to fully understand it.

the sum of a number and 7 is (x + 7)

3 times this is 3(x + 7)

is means the equal sign here </span><span>3(x + 7) = </span><span>

Two less then 5 times the number is 5x - 2.

Therefore, the answer is B, 3(x + 7) = 5x - 2</span>

Complete the Square <br><br> y= 3x^2+12x+20

stepan [7]

Answer:

$y = 3({x + 2)}^{2} + 8$

Step-by-step explanation:

The given function is

$y = 3 {x}^{2} + 12x + 20$

Factor

$y = 3({x}^{2} + 4x )+ 20$

Create a perfect square trinomial

$y = 3({x}^{2} + 4x + 4 ) - 3 \times 4+ 20$

Factor the the perfect square

$y = 3({x + 2)}^{2} - 12+ 20$

The vertex form is:

$y = 3({x + 2)}^{2} + 8$

alex41 [277]

Answer:

$0.8\ m$

Step-by-step explanation:

In this problem we know that

The scale is equal to

$\frac{1}{250}\frac{m}{m}$

so

by proportion

Find what will be the height of the scale model

$\frac{1}{250}\frac{m}{m}=\frac{x}{212}\frac{m}{m}\\ \\x=212/250\\ \\x= 0.848\ m$

Round to the nearest tenth of a meter

$0.848\ m=0.8\ m$
