Answer:
-0.8 and -8.2
Step-by-step explanation:
To solve a quadratic you first need to have one side of the equation equal to zero (because x-intercepts are when y is zero).
4x^2 + 24x + 13 = 2x^2 + 6x
2x^2 + 18x + 13 = 0
Then you can use the quadratic formula to solve for x. You will then come to
-18 ± sqrt(220) / 4
This will simplify out (rounding to the nearest tenth) to -0.8 and -8.2
Answer:
Greater Than
Step-by-step explanation:
Half of 15 is 7 1/2 and 13 is greater than 7 1/2
The lateral surface area is the surface area of the cube excluding the base and the top, which would make 4 square planes.
First we can find the area of a square plane:
4 1/2 x 4 1//2
=20 1/4 ft²
We can then multiply the area of plane by 4:
20 1/4 x 4
=81 ft²
Therefore the answer is 81 ft².

Answer:
9 cups
Step-by-step explanation:
We can use ratios to solve
1/3 cup red 4 cups red
----------------- = -------------------
3/4 cup yellow x cups yellow
Using cross products
1/3 *x = 3/4 *4
1/3x = 3
Multiply each side by 3
1/3 x * 3 = 3 * 3
x = 9
