-30+20=-10
Answer:
Monday - 4 hours
Wednesday - 14 hours
Step-by-step explanation:
'h' = hours worked on Monday
'2 + 3h' = hours worked on Wednesday
h + 2 + 3h = 18
4h = 16
h = 4 (Monday)
18 - 4 = 14 (Wednesday)
Answer:
Step-by-step explanation:
Step 1: The given expression is .
Step 2: Let us first know the law of exponents to add two exponents.
The base and the exponents must be the same to add two exponents.
Here base is w and the exponent is 2. They are same.
Step 3: Now add the coefficient of .
Hence the addition of the expression .
Surface area will consist of:
2 triangles, 3 rectangles:
Solving for triangles:
A=1/2bh
A=1/2(120)
A=60
60*2 gives us the surface area of both triangular sides.
Solve for rectangles:
(17*20)+(8*20)+(15*20)
(340)+(160)+(300)
(800)
800+120=920
The surface area of the prism is 920 square feet
