Answer:
Therefore, Lateral surface area of the pyramid= 
Step-by-step explanation:
The lateral surface area of the pyramid is the area of the all of its four triangular faces, excluding base :
Area of a triangle is:
Base= 3 inches
Height=8 inches
Lateral surface area of the pyramid:
Therefore, Lateral surface area of the pyramid=

Volume of a Cube Formula: V = a³
- <em>a</em> is any side length
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>a</em> = 5 cm
<u>Step 2: Find Volume</u>
- Substitute in variables [Volume of a Cube Formula]: V = (5 cm)³
- Evaluate exponents: V = 125 cm³
Answer:
x=89
Step-by-step explanation:
Okay so. because of the rules of parallel lines and their intersecting lines, we know that the upper angle and the lower angle are complimentary angles. This means that they add up to equal 180 degrees.
Because of this, we know that (x-3)+(x+5)=180
2x+2=180
2x=178
x=89
E. he did not multiply 3 by -1 correctly
The simplify expression is 9 - 3 + 6x = 6 + 6x
