Step 1: Distribute:
3(x+2) + 5(x+4) = 3•(x+2) + 5•(x+4)
= 3•x + 3•2 + 5•x + 5•4
= 3x + 6 + 5x + 20
Step 2: Combine Like terms
= 8x + 26
The answer is (1.5,10)
4x -y = -4
-(2x - y = -7)
-------------------
2x = 3
x = 3/2 or 1.5
3 3/4
= 3+ 3/4
= 3+ 0.75
= 3.75
The length as a decimal is 3.75 m~
Answer:
The correct answer is 75 cubic feet.
Step-by-step explanation:
Volume of each block of cube is 1 cubic foot. Since the block is of the shape of a cube, the side length is 1 foot.
Number of blocks needed to fill the bottom of the the chest is 25.
Height of the chest is 3 feet.
Therefore there are three layers to be filled by blocks. Each layer needs 25 blocks each. Thus number of blocks needed to fill the whole chest is 25 × 3 = 75.
Volume of 75 blocks = Volume of the chest = 75 × 1 = 75 cubic feet.
Therefor the volume of the chest is given by 75 cubic feet.
