No, if you multiply the factors in 3(5b-2) the equivalent expression would be 15b-6
Answer:
x=2 and y=3
Step-by-step explanation:
3x+2y=12
3(2) + 2(3)
6 + 6 = 12
12x+8y=48
12(2) + 8(3)
24+24=48
Answer: Your answer is c
Step-by-step explanation: The first thing you can do is add the two equations together to cancel out x
5x-2y=3
-5x+4y=9
added them together will get us 2y=12, from here divide 2 and get y=6
Plug 6 into the first equation and solve for x.
5x-2(6)=3
5x-12=3, add 13 to the other side
5x=15, divide 5 and get the answer
x=3
Answer:
357.5ft^3
Step-by-step explanation:
solve for bottom reticular prism
8 * 10 * 4
320ft^3
solve for top triangular prism
((3*5)/2)*5
37.5ft^3
add top and bottom
320+37.5
357.5ft^3
8x8 + 15x15 = y^2
64+225 = 289
take the square root of 289 which = 17
ANSWER = C. 17
