scZoUnD [109]

Answer:

Step-by-step explanation:

First, you plug -9 into g(x) and you get g(-9) = - 1. After that, you solve f(-1), which you then reach the solution of 0 by solving.

Find the area of the triangle given below.

Nimfa-mama [501]

<u>Given:</u>

A triangle with a base length of 22 ft and a height of 20 ft.

The area of the given triangle.

<u>Solution:</u>

The area of a triangle is obtained by multiplying $\frac{1}{2}$ with its base length and its height.

The area of a triangle $= \frac{1}{2} (b)(h).$

The height is the distance from the base to the highest point on the triangle and the length of the base is the base length.

The given triangle has a base length of 22 ft and a height of 20 ft.

The area of the triangle $= \frac{1}{2} (b)(h) = \frac{1}{2} (22)(20).$

$\frac{1}{2} (22)(20) = \frac{1}{2} (440) = 220$ ft².

The given triangle has an area of 220 ft².

What is the length of BG and LB need help will mark Brainliest

svlad2 [7]

we get x by setting up a proportion.

$\frac{12}{2x+2}$ = $\frac{21}{5x-1}$

then we cross multiply.

12(5x−1) = 21(2x+2)

60x − 12 = 42x + 42

18x − 12 = 42

18x = 54

plug in 3 for x for <u>LB</u>, which is <u>2x + 2.</u>

<u>LB </u>= 2(3) + 2 = 8

plug in 3 for x for <u>BG</u>, which is <u>5x - 1.</u>

<u>BG </u>= 5(3) - 1 = 14

<h2><u>Answers</u>:</h2><h2>LB = 8</h2><h2>BG = 14</h2>

There are 1,092 people who work in an office building. The building has 4 floors, and the same number of people work on each flo

IRISSAK [1]

Answer:

273 people.

Step-by-step explanation:

Given that,

Total number of people working on an office building = 1092

The building has 4 floors, and the same number of people work on each floor.

We need to find how many people work on each floor. Let there are n people in each floor.

n = Total number of people/Total number of floors

$n=\dfrac{1092}{4}\\\\n=273$

So, there are 273 people working on each floor.
