Answer:

127

Step-by-step explanation:

You can add 158 + 378 + 237 altogether for a total of 773

then subtract 773 from 900 for a total of 127

You can subtract 158 from 900 = 742

then subtract 378 from 742 = 364

and finally 237 from 364 = 127

Answer:

6x² - 7x - 3

Step-by-step explanation:

(f × g)(x) = f(x) × g(x), that is

(2x - 3)(3x + 1)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(3x + 1) - 3(3x + 1) ← distribute both parenthesis

= 6x² + 2x - 9x - 3 ← collect like terms

= 6x² - 7x - 3

When I worked at Southern it took me 8 minutes to get to work. Now, it takes me 26 minutes to get to work. What is the percent i

spayn [35]

Answer:

225%

Step-by-step explanation:

You can figure the percentage change from ...

percentage change = ((new value)/(old value) -1) × 100%

= (26/8 -1) × 100% = (3.25 -1) × 100% = 225%

What is the area of this triangle expressed as a monomial? height is 9x width is 6x

fiasKO [112]

Answer:

The area of triangle expressed as a monomial is $27x^{2}$

Step-by-step explanation:

we know that

The area of a triangle is equal to

$A=\frac{1}{2}bh$

In this problem we have

$h=9x\ units$

$b=6x\ units$

substitute

$A=\frac{1}{2}(6x)(9x)=27x^{2}\ units^{2}$

| 7 + m | - 4 > 8

cestrela7 [59]

Answer:

m > 5 or m < -19

Step-by-step explanation:

We are given the Inequality:

$\displaystyle \large{ |7 + m| - 4 > 8}$

First, add both sides by 4.

$\displaystyle \large{ |7 + m| - 4 + 4 > 8 + 4} \\ \displaystyle \large{ |7 + m| > 12}$

Absolute Value Property

$\displaystyle \large{ |a| = \sqrt{ {a}^{2} } }$

Given a = any expressions and b = any positive numbers, zero or any expressions.

$\displaystyle \large{ |a| = b \longrightarrow a = \pm b}$

From the Inequality, change > to equal

$\displaystyle \large{ 7 + m = \pm12}$

Subtract 7 both sides.

$\displaystyle \large{ 7 - 7 + m = \pm12 - 7} \\ \displaystyle \large{ m = \pm12 - 7}$

±12-7 can be 12-7 = 5 or -12-7 = -19

$\displaystyle \large{ m = 5, - 19}$

Refer to the attachment. The region is when the absolute value function is greater than constant function y = 12 or a blue horizontal line.

Since the absolute graph is above constant graph when x > 5 and x <-19.

Therefore,

$\displaystyle \large{ m > 5, m < - 19}$
