Let x equal a number
3x + 5 = 26
3x = 21
x = 7
the number is 7!
Answer: 18 cm2
Step-by-step explanation: the surface area of the cube is 54 cm2 and the rectangular prism is 72 cm2 so 72 - 54 = 18
The goal is to solve for y. Start by subtracting 2x from both sides. This gives you 8y=-2x+16. Now just divide both sides by 8, which gives you y=-2/8x+16/8. Finally, simplify this to y=-1/4x+2.
The prime factorization of 16 is 2⋅2⋅2⋅2.
The factors of 16 are all numbers between -16 and 16 that divide 16 evenly.−16,−8,−4,−2,−1,1,2,4,8,16
