Answer:

120 units ^3

Step-by-step explanation:

Volume=Area of triangular end times length.

Remember that the fromula from a triangular is multiplied by 1/2.

1/2 × 3 × 4 × 20= 120 units^3

is the result of your question.

Have a nice day☆

The answer is B.
**
The triangles on the two ends are congruent. So, to find the prism area, it is enough to take the area of one of the triangles and multiply it by the prism depth, which is 20 units.
Use the Pythagorean theorem to find the height of the triangle. 5^2 - 3^2 = 4^2, so the height is 4. Multiply half times height times base: 1/2 x 4 x 3 = 6. Multiply that by the depth, 20. 6x20=120. The answer is in cubic units, or units^3

Complete the square to solve the equation below.

Vinil7 [7]

9514 1404 393

Answer:

B. x = -6, x = 4

Step-by-step explanation:

The constant on the left wants to be 1, the square of half the x-coefficient. We can get it to be that value by adding 8 to the equation.

x² +2x +1 = 25

(x +1)² = 25 . . . . . . . rewrite the left side as a square

x +1 = ±√25 = ±5 . . . . take the square root

x = -1 ±5 . . . . . . . . . subtract 1

x = -6 or x = 4

Please find the fully simplified intercept form!!!! Will mark Brianliest !!!!!!!!!!!

Answer:

y = -1/3x - 8

Step-by-step explanation:

Slope intercept form:

y = mx + b

Use two points from the graph:

(0, -8) and (3, -9)

The first point is the y-intercept:

b = -8

Find the slope using the slope formula:

m = (y2 - y1)/(x2 - x1)
m = (-9 - (-8))/3 = -1/3

The equation is:

y = -1/3x - 8

A right triangle has an area of 18 square inches.If the triangle is an isosceles triangle, what are the lengths of the legs of t

Gnom [1K]

If it is isosceles, than the legs are the same. We will call them X. The formula for the area of a triangle is 1/2 (base * height). But the base and the height are both X. So the area (18) is equal to 1/2 (x * x), or 1/2(x^2). This means that 36 = x^2. Thus, the length of each side is 6 inches. You can check this work by plugging those into the formula for area. You will find that it equals 18.
