Answer:

99.33ft^2

Step-by-step explanation:

The surface area of a square pyramid is expressed as;

TSA = a²+2a√a²/4 + h²

Given that

a = 5ft

h = 7ft

Substitute

TSA = 5²+2(5)√5²/4 + 7²

TSA = 25+10√25/4 + 49

TSA = 25 + 10√(221/4)

TSA = 25 + 10(√55.25)

TSA = 25 + 10(7.433)

TSA = 25 +  74.33

TSA = 99.33ft^2

Hence the surface area of a square pyramid with side length 5 ft and slant height 7 ft is 99.33ft^2

Which equation represents a line that is parallel to y= -4x+3 and passes through the point (-3,2)
Katyanochek1 [597]

Answer:

The answer is

<h2>y =  - 4x - 14</h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

From the question

y = - 4x + 3

Comparing with the general equation above

Slope / m = - 4

Since the lines are parallel their slope are also the same

Slope of parallel line = (-3 , 2) and slope

- 4 is

<h3>y - 2 =  - 4(x + 3) \\ y + 2 =  - 4x - 12 \\ y =  - 4x - 12 - 2</h3>

We have the final answer as

<h3>y =  - 4x - 14</h3>

Hope this helps you

How to solve 105x2 +66x - 72 = 0 algebraically. Show work please
trapecia [35]

Answer:

Do pemdas, (parentheses, exponents, multiplication, division, addition and subtraction). But do whatever is first, which in this case is multiplication.

Step-by-step explanation:

Write the equation out.

    105 x 2 + 66x -72 = ?

    105 x 2 = 210

     210 + 66x - 72

    210 + 66x = 276x

     276x - 72 = 204

      ? = 204
