H(x) = x2 + 3x – 18

Rewrite the function by completing the square

h(x) = (x + 3/2)^2 - 81/4

Step-by-step explanation:

h(x) = x^2 + 3x – 18 (note the required use of " ^ " to indicate exponentiation)

Here 3 is the coefficient of the x term.  Take half of this 3 and square the result:  (3/2)^2 = 9/4.

Going back to h(x) = x^2 + 3x                       – 18

Add 9/4 and then subtract 9/4:

                        h(x) = x^2 + 3x + 9/4      - 9/4                       – 18

Rewrite this as  h(x) = (x + 3/2)^2 - 9/4 - 18, or

                          h(x) = (x + 3/2)^2 - 81/4

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
