Answer:
the first answer is correct and brainliest plsss (^_^)
Step-by-step explanation:
The width of a rectangle is going to be equal on both sides, as they’re parallel in a rectangular shape. We know the width is 86 yards, and we have two lots of these, therefore 86 multiplied by 2 is equal to 172 yards.
We still have two more sides, but once again, because this is a rectangle, those sides must be equal. Therefore if we subtract the 172 yards we know from the total perimeter of 438 yards we will end up with an answer of 266 yards. This figure is divided by two because we have a length on either side of the perimeter. Therefore the answer is 133 yards.
Hope this helps!
Answer:
B
Step-by-step explanation:
a is base edge
h is height or To find the volume of a square-based pyramid, use the formula V = A(h/3), where V is the volume and A is the area of the base.
2(3x + 5) = 5x + 14
6x + 5 = 5x + 14
x = 14-5
x=9
Answer:
(9, 0)
Step-by-step explanation:
We have to solve the system of equations given:
x + 2y = 9
x + 7y = 9
Firstly, lets solve for x in the 1st equation:
x = 9 - 2y
Now substitute this into 2nd equation to solve for y:
x + 7y = 9
(9 - 2y) + 7y = 9
9 -2y + 7y = 9
5y = 0
y = 0
Now replacing y = 0 into first equation, we can solve for x:
x + 2y = 9
x + 2(0) = 9
x + 0 = 9
x = 9
So, the solution is x = 9, y = 0
or
<u>(9, 0)</u>
