Answer:
Anserws : Square=36 , cube = 216
Answer:
800 cm^3
Step-by-step explanation:
An easy way is to cut the base up into two parts. Take a look at the drawing I added below for explanations!
Rectangle ACDG has an area of 28.
--> (12-5)(4) = (7)(4) = 28
Rectangle BFEG has an area of 72.
--> (10-4)(12) = (6)(12) = 72
So the total area of the base is 28 + 72 which is 100.
Base x Height is the volume, so it will be 100 x 8 (The height) = 800
So 800 cm^3 is your answer!
Answer:
f(10)=342
Step-by-step explanation:
f(10)= 3(10)^2+6(10)-18
complete your exponet first and multiply 6(10)
f(10)=3(100)+60-18
multiply the 3(100)
f(10)=300+60-18
add and subtract all the numbers together
f(10)=342
Answer:
One solution: (2.5,0)
Step-by-step explanation:
We can use substitution for the solution. Substitute y=2x-5 to -8x-4y=-20 so that you end up with -8x-8x+20=-20. Next you want to add like terms which will be -16x+20=-20, next you want isolate x by subtracting 20 from both sides and leaves you with -16x=-40. Divide -16 on both sides to fully isolate x and will leave you with x=2.5. Now substiture in 2.5 for x in y=2x-5 to get y=2(2.5)-5 which will then lead to y=0.
