C is your answer because you count 1 square a block
Answer:
90
Step-by-step explanation:
1/3 BH = 1/3(30)(9) = 90
Answer:
the answer is x=-5. a negative times a negative is a positive.
Answer:
B. y² – 5y = 750
C. 750 – y(y – 5) = 0
E. (y + 25)(y – 30) = 0
I'm assuming the 2 in the second option is supposed to be an exponent.
Step-by-step explanation:
Length = y
Width = y-5
Length × Width = Area
Area = <u>y(y-5)</u> = 750
<u>Distribute.</u>
y²-5y=750 (B is correct)
<u>If you factor the equation above</u>
(y + 25)(y – 30) = 0 (E is correct)
Area = y(y-5) = 750
<u>Subtract y(y-5) from both sides.</u>
750-y(y-5) = 0 (C is correct)
Answer:
The shape is plane, a rectangle
Step-by-step explanation:
The external figure, the cylinder is a rectangle in a two dimensional plane, so the cross section between two rectangles is also a rectangle
