Solve the equation. 5t^3 +40t^2 = -80t

Gnesinka [82]

Answer:

-5t2 + 40t - 3

Step-by-step explanation:

Step-1 : Multiply the coefficient of the first term by the constant 5 • 3 = 15

Step-2 : Find two factors of 15 whose sum equals the coefficient of the middle term, which is -40 .

-15 + -1 = -16

-5 + -3 = -8

-3 + -5 = -8

-1 + -15 = -16

1 + 15 = 16

3 + 5 = 8

5 + 3 = 8

15 + 1 = 16

A square pyramid has 1 square base and 4 triangular faces. Find its surface area. A. The area of the base is ________ square cen

Vanyuwa [196]

Answer:

See Explanation

Step-by-step explanation:

I will answer this question with the attached square pyramid

From the attached pyramid, we have:

$Base\ Length = 20m$

So, the base area is:

$Area = Length * Length$

$A_1= 20m*20m$

$A_1= 400m^2$

The dimension of each of the 4 triangles is:

$Height = 16.4m$

$Base = 20m$

So, the area of 4 triangles is:

$Area = 4 * 0.5 * Base * Height$

$A_2 = 4 * 0.5 * 20m * 16.4m$

$A_2 = 656m^2$

So, the surface area is:

$Area = A_1 + A_2$

$Area = 400m^2 + 656m^2$

$Area = 1056m^2$
