Answer:

20 +4√2

Step-by-step explanation:

Find the total area the regular pyramid = A + 1/2ps

A is the Base area

p is the perimeter of the base

s is slant height

A = 1/2 * 4 * 4

A = 16/2

A = 8

p = 4 + 4 + (√4^2+4^2)

p = 8 + √32

p = 8 + 4√2

s = 4

Substitute

TSA = 8 + 8 + 4√2 + 4

TSA = 20 +4√2

Hence the total surface area is 20 +4√2

the perimeter of an equilateral triangle is 39 centimeters. What is the length of an altitude of the triangle ?

victus00 [196]

Answer: $h = 11.26cm$

Step-by-step explanation:

Equilateral triangle has equal sides, let the side be $xcm$ , then the perimeter is $3x$

Therefore:

$3x = 39$

$x = 39/3$

$x = 13cm$

To find the altitude , we will apply Pythagoras theorem , that is

$13^{2}=h^{2}+6.5^{2}$

Therefore:

$h^{2}=13^{2}-6.5^{2}$

$h^{2}=169-42.25$

$h^{2}=126.75$

take the square root of both sides

$h = 11.26cm$

Two angles that have the sum of 180 degrees

evablogger [386]

Two angles that have the sum of 180 degrees are supplementary angles. If you need to find angle A, you just need to subtract angle B from 180 degree to find out the degree of the particular angle. Hope I helped.

If f(x) = 3^x + 10 and g(x) = 2x − 4, find (ƒ+g)(x)

galina1969 [7]

Answer:

3^x+12x-4

Step-by-step explanation:

(f+g)(x) = f(x) + g(x) = 3^x + 10x + 2x - 4 = 3^x + 12x - 4
