1) 4 divided by 7 = 0.57
2) 4 times 5 = 20 and 4 times 8 = 32
3) 20 plus 32 = 52
4) 0.57 times 52 = 29.64
5) answer : 29.64
i hope this is correct. i tried to break it down.
Answer:
90 sq inches
Step-by-step explanation:
The lateral area is the side area of the pyramid. In this case, there are 3 sides because the base is a triangle. Since the base is an equilateral triangle, all sides are of equal dimensions. So, the sides of the pyramid are also all of the same size, area.
We then just have to figure out the area of one of the side triangles, then multiply it by 3 to get the total lateral area of that pyramid.
We know how to calculate the area of a triangle: A = (b * h)/2
In this case, b = 5 in, h = 12 in. So,
TA = (5 * 12)/2 = 60 / 2 = 30
Each side triangle has an area of 30 sq inches.
LA = 3 * TA (since there are 3 sides)
LA = 3 * 30 = 90 sq inches

Step-by-step explanation:
The numerical length of ST is 16
<h3>How to determine the numerical length of ST?</h3>
The given parameters are:
ST = 2x + 6
TU = 4
SU = 4x
The above parameters can be represented as:
SU = ST + TU
This gives
4x = 2x + 6 + 4
Evaluate the like terms
2x = 10
Divide by 2
x= 5
Substitute x= 5 in ST = 2x + 6
ST = 2 * 5 + 6
Evaluate
ST = 16
Hence, the numerical length of ST is 16
