Please help with this

x^2 +8x+12

Step-by-step explanation:

The area of the blue is

x*x = x^2

The area of the pink is

x*6 = 6x

The area of the green is

x*2 = 2x

The area of the orange is 2*6 =12

Add them together

x^2 + 6x+2x +12

Combine like terms

x^2 +8x+12

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

the answer to the expression is 83
