Answer:

Option (B) is correct.

The simplified form of the given expression 9\left(a\:+\:b\right)\:+\:4\left(3a\:+\:2b\right) is 21a+17b

Step-by-step explanation:

 Given: expression 9\left(a\:+\:b\right)\:+\:4\left(3a\:+\:2b\right)

We have to simplify the given expression 9\left(a\:+\:b\right)\:+\:4\left(3a\:+\:2b\right) and choose the correct option from given options.

Consider the given expression 9\left(a\:+\:b\right)\:+\:4\left(3a\:+\:2b\right)

Apply distributive rule, a\left(b+c\right)=ab+ac

We have,

=9a+9b+12a+8b

Adding like terms,

LIKE TERMS are terms having same variable with same degree.

9a+12a=21a\\\\ \:9b+8b=17b

We have,

=21a+17b

Thus, The simplified form of the given expression 9\left(a\:+\:b\right)\:+\:4\left(3a\:+\:2b\right) is 21a+17b

Find the measure of each angle indicated.<br> A) 95°<br> C) 26°<br> B) 92°<br> D) 20°
riadik2000 [5.3K]

Answer:

D) 20°

Step-by-step explanation:

Using the triangle sum theorem, you know that every triangle's interior angles add up to 180°. Therefore the bottom triangle's missing angle can be found by giving it the variable x.

57° + 30° + x = 180°

Simplify: 87° + x =180°

x=93°

By the vertical angles theorem, the vertical angle directly across this angle is congruent to this one. Meaning that the top triangle's angle are 67°, 93°, and unknown, which we can assign y. We can use the same method from above here.

67° + 93° + y = 180°

Simplify: 160° + y = 180°

y=20°

steposvetlana [31]
The first consignment shows no association between the t-shirt size and the profit. 

In the second consignment, the bigger the t-shirt size, the smaller the profit. There is an inverse relationship between the two variables. 

In the third and fourth consignment, the bigger the size, the larger the profit. There is a direct relationship between the two variables.

Why does the equation (x-4)^2-28=8 have two solutions?
Aliun [14]
<h3>Answer:</h3>

For your first answer it is because they are two different ways to solve the equation

<h3>Step-by-step explanation:</h3>

For Example!

<h2>Solution 1:</h2>

(x-4)² – 28 = 8The 8 is positive making it a different equation (this is like absolute value). (I am assuming you know the answer to the probelm)

<h2>Solution 2:</h2>

(x-4)² – 28 = -8

The 8 could be negative meaning that when you add the 28 to the right side it is -8+28 which will be a negative!
