Answer:

a \: 3x - 6 \\ b \: 2y + 8 \\ c \: 8x + 24

Step-by-step explanation:

All we have to do is multiply accordingly. I'll use a for an example.

So for the value before the perentheses we multiply that by all of the values in the perentheses.

3x \:  and \: - 6

So the correct answer would be

3x - 6

You can use the same strategy for all the questions, but I'll just answer those straight away.

Also you may notice I put the variable before the constant in question c because the variable should always go before the constant in expressions and equations.

Type the missing numbers in this sequence:<br> -99, -97,<br> -93,<br> -89,<br> -87
iragen [17]

Answer:

Hope I helped ꒰⁎˃ ॢꇴ ॢ˂⁎꒱

Step-by-step explanation:

-99, -97, -93, -89, - 87

Lets look at the differences

+2, +4, +4, +2

Doesn't really seem like a specific pattern, but I can assume it goes like +2, +4, +4, +2, +4, +4, +2, +4, +4,

We are on +4 then, so the answer would be (-87)+4, which is -83

This sequence follows no pattern though, so if there is an option that there is not enough info to solve the sequence, pick that.

Julli [10]

Answer:

  A)  x is less than 4 AND x is less than 1

Step-by-step explanation:

It's all about understanding the meaning of the English words involved.

A) any member of the solution set must be less than 1 and less than 4. Only numbers less than 1 can satisfy both requirements. (This is the correct choice.)

__

B) members of the solution set may be less than 1 or may be greater than 3. Numbers less than 1 are part of the solution set, but not all of it.

__

C) members of the solution set are required to be both greater than 3 and less than 1. There are no such numbers. The solution set is the empty set.

__

D) members of the solution set may be less than 4 or less than 1. Any number less than 4 will be a member of the solution set.

please hurry .The side of Mr. Miller’s barn has a length of 27 feet and an area of 656.1 square feet. How wide is the side of Mr
Art [367]

Answer:

24.3

Step-by-step explanation:

area of a rectangle =length*width

if we know at least the 2 quantities already

total area = 656.1

and one of the sides = 27

we have to divide the are by one of the sides to get the remaining side

width = area/length

656.1 divided by 27 equals 24.3
