Answer:
A
Step-by-step explanation:
The area for a parallelogram is given by the formula:
Where b is the base length and h is the vertical height.
The base length is 6 and the height is 10 (if you flip the figure 90 degrees). So:
Multiply:
Our answer is A.
And we're done!
Answer:
19.5
Step-by-step explanation:
9 * 13 = 117, 2b = 6, so 117/6 = 19.5
Check the picture below.
the ball hits the table, when it hits "the ground" or goes all the way back down, at that point, the height of the ball is 0, thus h = 0.
25(3x-y)²-16(5x+3y)²=25(9x²-6xy+y²)-16(25x²+30xy+9y²)=
=225x²-15xy+25y²-400x²-480xy-144y²=-175x²-630xy-119y²
