Answer:
you can try adding the adding angles up to 180
or if its graphed you can count the units
Step-by-step explanation:
and know that all four sides are congruent and diagonals are perpendicular
i tried :)
Answer:
No, she cannot completely cover the footrest.
Step-by-step explanation:
First of all, we need to find the total surface area of the prism to be covered using the cotton cloth
the total surface area of the prism is
A = 2wl + 2lh + 2hw,
l is the length of the prism = 18 in,
w= width of the prism = 12 in,
h is the height of the prism = 10 in
hence 
We need to convert the area of the fabric to be in the same unit as that of the prism
Area of cotton fabric = 
since the surface area of the foot rest is more than the area of fabric she has, she cannot completely cover the footrest
The increase of volume = volume of the cube = 1 cubic foot = 1728 cu ins
Area of the base = 12 sq ft = 12 * 144 = 1728 sq ins
The height of increase = 1728 / 1728 = 1 inch Answer
The answer is negative 5 because you subtract 12 from each side to get 5x=-25 and -25 divided by 5 is negative 5
The first one is C and the second one is B
