Work:
Multiply a and 7
Multiply a and 1
The a just gets copied along.
7*a evaluates to 7a
8+7*a evaluates to 8+7a
8 + 4 = 12 which goes to 12+7a
(8+7*a)+4 evaluates to 12+7a

***The final answer is 12+7a***

Need help on this!!!
Helga [31]

Answer:

Step-by-step explanation:

Range goes from the lowest point on a graph to the highest point, not including anything in between those 2 extremes. We will evaluate the quadratic for the values given. First f(2):

f(2)=(2)^2-5 so

f(2) = -1

Now, f(4):

f(4)=(4)^2-5 so

f(4) = 11

Now, f(7):

f(7)=(7)^2-5 so

f(7) = 44

The lowest y value is -1 and the highest is 44, so the range is from -1 to 44 (I can't tell which of your choices reflects that because it's too small!)

Use the first three triominoes to find the missing number in the fourth triomino.
Nonamiya [84]
Answer: 28

Since we know there is a pattern of 20, 22, 24, and 26, we can see that there is a difference between each of the numbers of +2. Therefore, 26 + 2 = 28

- Hope it helps!
