Answer:
8N-2=33+N
Step-by-step explanation:
Solution
For this case we can take square root in both sides and we have:
![3x-5=\pm\sqrt[]{19}](https://tex.z-dn.net/?f=3x-5%3D%5Cpm%5Csqrt%5B%5D%7B19%7D)
And solving for x we got:
![x=\frac{5\pm\sqrt[]{19}}{3}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B5%5Cpm%5Csqrt%5B%5D%7B19%7D%7D%7B3%7D)
then the solutions for this case are:
B and E
Answer:
B. 150 yards
Step-by-step explanation:
Area of a Triangle = .5 * Base * height
So we need the height of the triangle, or the missing side.
We have to use Pythagorean Theorem to solve this:
A^2 + B^2 = C^2
15 ^ 2 + B ^ 2 = 25 ^2
b^2 = 25^2 - 15 ^ 2
b^2 = 625 - 225
b^2 = 400
sqrt (400) = 20
The missing height is 20. Now we plug it into 1/2 * b * H
.5 * 15 * 20
7.5 * 20 = 150
150 Yds
Answer:
246 ft^2
Step-by-step explanation:
First, break it into smaller rectangles:
3*6=12
6*9=54
15*12=180
Add the areas together
12+54+180=246
The area of the figure is 246 ft^2
Answer:
x= -1
Step-by-step explanation:
8x - 16 = -4x - 4(1-6x)
8x - 16 = -4x - 4+24x
8x - 16 = 20x-4
8x - 16+16 = 20x-4+16
8x = 20x+12
8x-20x = 20x-20x+12
-12x=12
Divide both by -12, and you get -1.
