8x-9y+16x+12y

How do I solve this equation

Answers

Answer 1
Answer: to solve this equation go to www.tigeralgebra.com
Answer 2
Answer: combine like terms (x's go with x's and y's go with y's) take the sign in from of the value and combine 8x+16x =24x  and -9y+12y=3y (combine only works if the variables have the same  exponent ( u can combine x and x(because they have an understood exponent of 1)  but not x and x^3)

Question #7MultipleChoice Score:
The volume of a rectangular prism is 288 ft3. If its height is 6 feet and its length is 8 feet, what is its width?
A. 6 feet B. 8 feet C. 9 feet D. 12 feet
Question #8MultipleChoice
A cube is 6 feet on each side. What is its volume?

Answers

Q1: The answer is A. pyramid.
A pyramid has one polygon base. A prism has two polygon bases. A cone has one circular base. A cylinder has two circular bases.

Q6: The answer is false.
Surface area of a rectangular prism is:
A = 2(wl + hl + hw)
A1 = 2(4*5 + 6*5 + 6*4) = 2(20+30+24) = 2*74 = 148
A2 = 2(6*4 + 5*4 + 5*6) = 2(24+20+30) = 2*74 = 148

Q7. The answer is A. 6 feet
The volume of rectangular prism is:
V = w * l * h
w = ?
So, just replace the knowing facts:
288 = w * 8 * 6
288 = w * 48
w = 288/48 = 6

Q8: The answer is 216 ft³
The volume of the cube is:
V = a³
Since a = 6, then:
V = 6³ = 216

Answer: #1 is pyramid


Step-by-step explanation: a pyramid can have any polygon as a base
