Answer: Choice A
A trapezoid has only 1 pair of parallel sides, but a parallelogram has 2.
=============================================
Explanation:
These terms are just things you memorize. A diagram of two examples is shown below. The example shows a non-rectangular parallelogram, but you could go with rectangles or squares if you wanted to.
The top and bottom have area (2.4 ft)² = 5.76 ft².
The sides have area (4*2.4 ft)*(3.4 ft) = 32.64 ft².
The the total area is (2*5.76 +32.64) ft² = 44.16 ft². All but the bottom area is then 44.16 ft² -5.76 ft² = 38.40 ft².
The ratio (all but bottom area)/(total area) is then
38.40/44.16 ≈ 87.0%
X^2 + 10x + c
Use the number in front of x, (10), to help you.
First, divide 10 by 2:
10/2 = 5
Second, square the answer, (5).
(x+5)(x+5) = 25
Answer: c=+25
Answer: 10
Explanation:
formula for hypotenuse : a^2+b^2=c^2
8^2+6^2=c^2
64+36=c^2
100=c^2
so we find the square root of 100 and its is:
c=10
