1.) To find the surface area, we want to find the area of each side, then add them all up together:
Area of base=lwA=(5)(5)A=25 cm²
Area of triangle=1/2bhA=(1/2)(5)(12.5)A=31.25 cm²
Since the 4 triangles have the same area, we can multiply the area we found by 4 and then add the area of the square:
SA=(4)(31.25) + 25SA=125+25SA=150 cm²
2.) <span>To find the volume use the formula:
V=(1/3)lwh
V=(1/3)(5)(5)(12.5)
V=104.167 cm^3</span>
-12 x -12 = 144 I’m pretty sure if not then it is something different
Answer:
0.75%
Step-by-step explanation:
Convert the fractions and then multiply by 100.
Answer:
x = 0
Step-by-step explanation:
(x)=5x+19(x)=-2x+15
We move all terms to the left:
(x)-(5x+19(x))=0
We add all the numbers together, and all the variables
x-(+24x)=0
We get rid of parentheses
x-24x=0
We add all the numbers together, and all the variables
-23x=0
x=0/-23
x=0
Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
Part 1) we have
----> equation A
----> equation B
substitute equation B in equation A

Applying property of exponents



therefore

Part 2) we have
----> equation A
----> equation B
substitute equation B in equation A

Applying property of exponents



simplify

therefore
