Answer:
The second one
Step-by-step explanation:
A linear function will always increase or decrease by the same amount:
The first one adds eight for every increase of 1 in the x value
The third one subtracts three for every increase of 1 in the x value
However,
The second one starts by adding three, and then adds 1.5 for the rest
The second table is nonlinear
To find the surface area of this figure, we simply have to add up the individual areas of the shapes that make up the figure.
Surface area = 4(area of triangle) + area of square
Surface area = 4 ( 1/2 * base * height) + side^2
Surface area = 4( 1/2 * 6 * 7) + 6^2
Surface area = 4 (3 * 7) + 36
Surface area = 4(21) + 36
Surface area = 84 + 36
Surface area = 120 cm^2
Hope this helps!
Answer: (10-2) + 1/4
Step-by-step explanation: This expression is 10-2 which si 5 and then 1/4 as great would be bigger than that so you add.
Answer:
Step-by-step explanation:
We want to factor the expression 
.
First, notice that this is in quadratic form. In other words, both the exponents have even power.
Therefore, we can make a substitution to simplify the expression.
So, let’s let 
.
Our expression is the same as:
Substitute:
Now, we can factor like normal. We can use -1 and -4. Therefore:
We can now substitute back u:
Both of these can be factored furthered using the difference of two squares:
Therefore, we will have:
And we are done!
