Answer:
m=
simplest form if you need it as a decimal its m=7.6
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
x^2 -8x=0
rewrite in this form and add 16 to both sides:
x² + 2(- 4)x + 16 = 0 + 16
(x - 4)² = 16 ( take square root of both sides )
x - 4 = ± 4
x = 4 ± 4
x=8 , x= 0
Answer: 100 x the original surface area of the box.
Discussion: Note that a box implies three dimensions. However, when dealing with surface area, we are dealing only with two dimensions. Therefore, scaling up a box where we have sides a, b, and c, by a factor of 10, we increase each side by a factor of 10. The scaled up box now has each of those dimensions as 10a, 10b, and 10c. Whereas the VOLUME is increased from (a x b x c) to (10a x 10b x 10c), the SURFACE AREA is increased from 2(a x b) + 2(a x c) + 2(b x c) to 2(10a x 10b) + 2(10a x 10c) + 2(10b x 10c). The SURFACE AREA is therefore kept in only square units, while VOLUME is in cubed units.
To help you graph this, get y alone in both equations. If you don't have a graphing calculator, use the Desmos graphing calculator online.
So, you will end up graphing this:
y=8-x
y=(34/3)-(5/3)x
They will meet at (5,3)
Answer:
51 × 5 = L
L = $255
Step-by-step explanation:
First, we can have "L" equal the amount of money Lee saved.
L = amount of money Lee saved
If Jessi saved 5 times as much, <u>you can find out how much money Lee saved by multiplying how much Jessi has by 5</u>.
Jessi has $51, so the equation would be <u>51 × 5 = L</u>
51 × 5 = 255
So, Lee has $255 saved.
