Answer is B
= (-2x^2 - 2x + 1) - (x + 1)
= -2x^2 - 2x + 1 - x - 1
= -2x^2 -3x
Answer:
5,5
Step-by-step explanation:
it has the longest side
Answer:
A
Step-by-step explanation:
f(x)=x^2-4x+3
x coordinate: -b/2a
-(-4)/2(1)=4/2=2
and to find the y coordinate just plug in the value of -b/2a for x and solve for y
1. To find the length of the edge, you will divide the total distance of 36 cm between the 4 edges that are shown.
36/4 = 9 cm per edge.
2. To find the surface area, find the area of one square (9 cm x 9 cm = 81 square cm), and multiply it by 6.
81 square cm x 6 = 486 square cm
486 square cm is the surface area.
