Answer:

Step-by-step explanation:

We can use to formula of finding the area of a trapezoid in this problem.

Formula: [(b1 + b2)/2] *h, where b1 and b2 are the bases and h is the height.

b1 can be the bottom base, which has a length of 21 units.

b2 can be the top base, which has a length of (21-9-3)+3 = 12 units.

h has a length of 8, since it is the height.

Plugging these into the formula, we can see that the area of the entire figure is (21+12)/2 * 8 = 33/2 * 8 = 33*4 = 132 units².

Hope this helps! :)

Answer:

132 square units

Step-by-step explanation:

First, I would figure out the areas of the right triangles

Left triangle: 1/2(6x8) =24 units²

Right triangle: 1/2(8x3) = 12 units²

entire rectangle between triangles: 12x8 = 96 units²

add all areas together: 24+12+96 = 132 units²

What is the smallest solution to the equation 3x<img src="https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20" id="TexFormula1" title=" x^

topjm [15]

IF you mean $3 x^{2} -16=131$ , then the following would be a solution:

First add 16 to both sides of the equation:
$3 x^{2} = 147$

Now divide both sides of the equation by 3:
$x^{2} =49$

Take the square root of both sides to solve for "X", or simply solve by inspection: "what number(s) can be squared to get 49?"

Answer: -7 and 7 So the smallest solution would be "-7"

Answer:

681ft^2

Step-by-step explanation:

Start by finding the area of the whole thing with the missing triangle:

33 x 22 = 726

Then find the area of the triangle. You can do this by first finding out the side lengths of the triangle:

33 - 24 = 9 and 22 - 12 = 10

Then multiply both sides and divide by two because it is a triangle:

10 x 9 = 90 90/2 = 45

Then subtract the area of the triangle from the rectangle:

726 - 45 = 681

SashulF [63]

Final Answer: $w = -4$

Steps/Reasons/Explanation:

Question: Solve $-0.6w = 2.4$ .

Step 1: Divide both sides by $-0.6$ .

$w = -\frac{2.4}{0.6}$

Step 2: Simplify $\frac{2.4}{0.6}$ to $4$ .

$w = -4$
