First we have to distribute the parentheses on the left side, 2*x is 2x and 2*-3 is -6, so now the equation is 4x+2x-6 = 8x+12
Then, we can add together the two x's on the left side,
so now we have 6x-6 = 8x+12 Subtract 12 from both sides and
you get 6x -18 = 8x Then you can subtract 6x from both the sides and get
-18 = 2x Now we can divide both sides by 2, and the final answer is -9 = x
Since they are not the same and the two sides aren't unequal, there is one solution(:
Hope this is helping you(:
Answer:
A solid with surface area 216 square meters and volume 324 cubic meters is dilated by a scale factor of k to obtain a solid with surface area 24 square meters. Find the value of k which leads to an image with the given surface area. Find the volume of the dilated solid.
Answer:
- Yes, the ball reaches the height of 64 ft
Step-by-step explanation:
<u>Given function</u>
<u>The maximum value is at vertex and the x-value of the vertex is:</u>
<u>Finding the maximum height the ball can reach:</u>
- h(2) = -16(2²) + 64(2) = -64 + 128 = 64
The answer is yes
Answer:
Statement 3: A cone is one-third the size of a cylinder with the same height and radius.
Statement 4: A cone has a circular base.
Step-by-step explanation:
Statement 3: A cone is one-third the size of a cylinder with the same height and radius.
Statement 4: A cone has a circular base.
The parabola x = y² - 9 opens to the right. The vertex is at (-9,0). Since y has no negative coefficient, the parabola opens to the right. Parabola is two-dimensional and is a mirror-symmetrical curve. It is more or less U-shaped.
