Answer: x=0.4
Step-by-step explanation:
0.5x + 4+0.9x = x+5

0.4x=1
X=0.4
Hope this helps
Answer:
no.
Step-by-step explanation:
since 2 of the sides are much longer than the shorter sides, diagonals of a rectangle will not intersect at a right angle (perpendicular) whereas a square, with all sides equal, would. This is because the distance from the center to each of the corners is the same for each corner.
Multiply 10 x 20 and change the sign
-200
Break down the figure into 2 separate rectangular solid and find each volume and sum it.
<u>Volume of smaller step:</u> The volume of any rectangular solid is given by,

So we have 
<u>Volume of larger step:</u> The only dimension that is different than the smaller step is of the height, which is 6. So we have,

Hence, the volume of the whole figure, in cubic inches, is
. Answer choice B.
