Answer:
area= 59.5 perimeter=31.6
Step-by-step explanation:
the area of the square is 49 because 7x7=49 and the area of the triangle is 3x7/2 because it is half of a rectangle so it is 10.5 + 49 = 59.5 and perimeter you add all the sides so 3+7.6+7+7+7= 31.6
Answer: Choice A
Proof:
Replace x with 1 and y with 2. This is because (x,y) = (1,2) so x = 1 and y = 2.
Doing both replacements and simplifying leads to...
2*x - y = 0
2*1 - 2 = 0
2 - 2 = 0
0 = 0
That confirms (x,y) = (1,2) is a point on the line.
It confirms (1,2) is a solution to the equation.
First we must set up the problem
(n)+(n+1)+(n+2)=8
26.50 × 20%
= 26.50 × 0.2
= 5.30
26.50 + 5.30
= 31.80
since charissa doesnt want to leave coins/pennies on the table, you would round it up.
31.80 would then epual 32.00 due to the tenths being above 5 (an 8)
