Answer:
D. 9, 12, 15
Step-by-step explanation:
You can use the Pythagorean Theorem to solve.
a^2 + b^2 = c^2
9^2 + 12^2 = c^2
81 + 144 = 225
Remember, c is squared.
The square root of 225 is 15.
D is the only answer that is correct.
Answer:
$7.5
Step-by-step explanation:
Let
Quantity of stickers=x
Price of stickers=y
5 stickers cost $3
12 stickers cost $y
x/y = x/y
5/3 = 12/y
Cross product
5y=12*3
5y=36
Divide both sides by 5
5y/5 = 36/5
y=7.5
12 stickers= $7.5
Therefore, the price of 12 stickers= $7.5
Only polygons with same length and angle measure can be regular polygon. so in here the right ones are A and D they both explain the same thing (?)
