Step-by-step explanation:
9514 1404 393
Answer:
66 cm²
Step-by-step explanation:
The area of the polygon is the sum of the areas of the triangle and the rectangle it sits on. The dimensions of the triangle can be found by examining the top/bottom dimensions shown and the left/right dimensions shown.
The width (base) of the triangle is the difference between the lengths of the bottom and top horizontal lines: (12 -9) cm = 3 cm.
The height of the triangle is the difference between the lengths of the left and right sides of the figure: (9 -5) cm = 4 cm.
The dimensions of the rectangle are shown a the bottom and the left sides of the figure.
triangle area = 1/2bh = 1/2(3 cm)(4 cm) = 6 cm²
rectangle area = LW = (12 cm)(5 cm) = 60 cm²
Total polygon area = 6 cm² + 60 cm² = 66 cm²
Answer:
$67.41
Step-by-step explanation:
We want to find out how much 30% off of $96.30 is. To do that, we need to first multiply $96.30 to find out how much 30% would be. Don't forget to change 30% into its decimal form (30% - > .3).
96.30 x .3 = 28.89
This means that Steve got $28.89 dollars removed from his final bill. To find the actual final bill, subtract 28.89 from 96.30.
96.30 - 28.89 = $67.41
To find the answer, we substitute in the values of y and x
(8 × 3) - 6 = 24 - 6 = 18
So your answer is 18

D is a prime polynomial.
The best way to figure this out is by attempting to factor them all. Each of them factors into perfect squares except for D.
A)
x^2 - 6x + 9 = (x - 3)^2
B)
x^2 + 16x + 64 = (x + 8)^2
C)
4x^2 + 20x + 25 = (2x + 5)^2
D we can also tell won't have a perfect square like that because it ends in a negative number. No number multiplied by itself is negative.
