Answer:
4. (12x)(5x) = 60x^2 because x times x is x to the power of 2
5. F are the front not the back meaning (6)(11) which is 66
1/8
3* 1 / 8 * 3
3/24
1/8 = 3/24
3/24 ≠ 3/20
Since 3/24 ≠ 3/20, 1/8 and 3/20 do not form a proportion.

Answer:
16√231 units²
Step-by-step explanation:
Because the triangle is isosceles, we can easily find the height. Splitting the triangle in half gives us a right triangle whose hypotenuse is 10 units, and one of the legs is 5 units.
We can use the Pythagorean Theorem: x² + 5² = 16² -> x² = 231 -> <em>x = √231</em> (can not be simplified)
Now that we know the height, we can solve for the area. The base is 16, and the height is √231.
That gives us 16*√231 = 16√231 units².
(Heron's formula can be used, but in this situation, doing this takes less time)
Answer:
x=2
Step-by-step explanation:
First, you want to distribute -2 into both terms in the parenthesis.
-2(x-3) = -2x+6
Now you have -2x+6=-3x+8
Next, I want to only have x on one side of the equation to solve it, so I will add 3x to both sides.
x+6=8
Finally, I subtract 6 from both sides so x is alone on one side of the equation
x=2
Now I know x = 2. To double check this, I can substitute 2 in for x in the original equation.
-2(2 - 3) = -3(2) + 8
-2(-1) = -6 +8
2 = 2
Both sides equal eachother, so x = 2 is the correct solution.
