Answer:
"Surface area of any pyramid = area of base + area of each of the lateral faces.
If the pyramid is a regular pyramid, we can use the formula for the surface area of a regular pyramid."

Answer:
7(x-2)(x+2)
Step-by-step explanation:
7x^2 -28
Factor out a 7
7(x^2 -4)
The terms inside the parentheses is the difference of squares, so it is factorable (a^2-b^2) = (a-b)(a+b)
7(x-2)(x+2)
2x+1=9
Your going to always try to leave the x variable alone.
2x+1=9
-1 -1
2x=8
/2 /2
x=4
Answer:
Perimeter: 310 units
Step-by-step explanation:
If x=4 and y=5, then the measure of the lengths would be..
8y+19= 8(5)+19= 59
8x+64= 8(4)+64= 96
13y-6= 13(5)-6= 59
16x+32= 16(4)+32= 96
To check if all these measurements are congruent, we can see if they match up with the measure of their parallel line, which they do in this case because 59=59
96=96
To find the perimeter of any shape, we add all the side lengths together
59+59+96+96= 310

Step-by-step explanation:
150=45
150 -25=x
:150=45
125=x
cross multiply
150x/150=5625/150
x=38 days
