Answer:
168 ft²
Step-by-step explanation:
The area of the two triangular bases is ...
total base area = 2×(triangle area) = 2×(1/2)bh = (6 ft)(4 ft) = 24 ft²
The lateral area of the prism is the product of the triangle perimeter and the height of the prism.
lateral area = (6 ft + 5 ft + 5 ft)(9 ft) = 144 ft²
The surface area is the sum of the base area and the lateral area:
surface area = base area + lateral area
surface area = 24 ft² +144 ft² = 168 ft²
The surface area of the prism is 168 square feet.
Answer:
Step-by-step explanation:
Answer:
Jessiah has 14 pencils
Miles has 28 pencils
Grace has 8 pencils
Step-by-step explanation:
I'm going to assume that you mean Jessaih instead of Jessia because otherwise it would be impossible to solve
Let the # of Jessaih's pencils equal j, # of Grace's pencils equal g, # of Miles' pencils equal m,
j=g+6
m=2j
So m=2(g+6) or 2g+12
Therefore, g+g+6+2g+12, or 4g+18=50, so g = 8
j=8+6, which is 14
m = 2(14), which is 28
Answer:
x²+y²+z²+2xy-2yz-2zx
Step-by-step explanation:
{(x+y)-z}^2
=(x+y)²-2(x+y)z+z²
=x²+2xy+y²-2zx-2yz+z²
=x²+y²+z²+2xy-2yz-2zx
Answer:
$37 3/8
Step-by-step explanation:
Add the rise to the opening price to find the closing price.
33 1/8 + 4 1/4 = (33 +4) + (1/8 +2/8) = 37 3/8 . . . . . . dollars per share
