Answer:
- 63 ft²
- h = 2A/b; h = 7 ft
Step-by-step explanation:
1. Put the values where the variables are in the formula, then do the arithmetic.
... A = (1/2)bh = (1/2)(18 ft)(7 ft) = 63 ft²
2. Divide by the coefficient of h. Substitute the given values and do the arithmetic.
... A = (1/2)bh
The coefficient of h is b/2, so we divide by that—or multiply by its inverse, 2/b.
... 2A/b = h
Substituting the given numbers, you have ...
... 2(28 ft²)/(8 ft) = h = 7 ft
The height of the triangle is 7 ft.

Answer:
{1,6}
Step-by-step explanation:
the second box is always where the y values/range are
x3 × x3 × x3 (I'm assuming you mean 3x for that) is equal to 9x^3. x3 × 3 × 3 is equal to 9x. They are not equivalent because one expression has 3x, 3 times, because you are multiplying the 3's together, and adding the x's three times, you get 9x^3. The x's are important since it differentiates between both expressions. 3x × 3 × 3, there is only one x in it, so it is just 9x. Does 9x=9x^3? No.
Answer:
the second option is the correct answer
