I got you, give me a few minutes
1st one: 6x+12+6y
2nd one: -12a-20b
4th one: 2x times 18
Step-by-step explanation:
Answer:
88 score.
Step-by-step explanation:
Given:
To get a B in math, Alexandria Pappas must<u> average 80</u> on five tests.
Scores on the first four tests were <em>82, 74, 82, and 74.</em>
Question asked:
What is the lowest score that she can get on the last test and still get a B?
Solution:
Let lowest score she can get on the last test = 
As we know:

By cross multiplication:-

Thus, she can get 88 score on the last test to get a B in math.
The image is missing, so i have attached it.
Answer:
x = 56.44°
Step-by-step explanation:
From the attached image, we can see that this is a right angle triangle which has opposite, adjacent and hypotenuse as sides. Since we want to find the angle x, thus, we can make use of trigonometric ratios.
From the attached image, the side opposite to angle x is 10ft and the hypotenuse is 12 ft.
From trigonometric ratios, we know that, sin x = opposite/hypotenuse
So, sin x = 10/12
x = sin^(-1) (10/12)
x = sin^(-1) 0.8333
x = 56.44°

<h2>Given:
</h2>

<h2>
Step-by-step explanation:</h2>
In this problem, we need to find the value of the given expression for which we need to simplify the given expression.

We need to solve the numbers within the parentheses.

We can bring the constant one side and variables another side.

Taking fourth root for ‘8’ and ‘3’ will give numbers which are very tough to solve further.
Since, we cannot solve the above equation further. The value of the given equation remains,

Answer:
(-1)(-3)
Step-by-step explanation:
When two negatives are multiplied it always equals a positive making it the only one that equals positive 3.
