Answer:7
Step-by-step explanation: 10 +10 +x+x=34
20+2x= 34
-20 20
2x=14 x=7
Answer:
-3.5 or -6
Step-by-step explanation:
2x^2+19x+40=-2
2x^2+19x+40+2=0
2x^2+19x+42=0
2x^2+(12+7)x+42=0
2x^2+12x+7x+42=0
2x(x+6)+7(x+6)=0
(x+6)(2x+7)=0
either,
x+6=0
x=-6
or,
2x+7=0
2x=-7
x=-7/2
x=-3.5
The answer is 2 y= 2 so 3•2=6 6-4=2
As already mentioned, the volume for a rectangular prism, namely a box in this case, is just the product of its dimensions, length * width * height.

now, as far as another one... hmm is easier if you post in the channel, that way I can include any graphs if needed or tables and such.
so, what happens if you double up the dimensions?

notice, how many times the new size is, is 8 times the original.
