.63 i mean it is not that hard
Answer:
if u substract the equations u get 4x = 1, therefore x = 1/4
Step-by-step explanation:
(8x + y) - (4x + y) = 5 - 4
4x = 1
x = 1/4
The dimensions of the rectangle is 2.45 m by 5/8 m
thus the area will be:
A=length*width
A=2.45×5/8
A=1.53125 m²
Perimeter will be:
P=2(L+W)
P=2(2.45+5/8)
P=2(3.075)
P=6.15 m
D. (7,0)
The original coordinates were (0,7)y and (1,5)x then I rotated it 90 degrees and the coordinates were (7,0)y and (5,1)x
Answer:

Step-by-step explanation:
Given that,
The radius of a cylinder, r = 5 cm
Height of the cylinder, h = 5 cm
We need to find the lateral surface area of the cylinder. The formula for the lateral surface area of the cylinder is given by :

Put all the values,

So, the lateral surface area of the cylinder is
.
