a dime ....... is what is ten cents and tax a penny
4x = y
2x^2 - y = 0
2x^2 - 4x = 0
2x(x - 2) = 0
2x = 0 or x - 2 = 0
x = 0 or x = 2
y = 4(0) or y = 4(2)
y = 0 or y = 8
Therefore, solution set is {(0, 0), (2, 8)}
Answer:
Step-by-step explanation:
Surfae area
we have 5 faces for the top shape
6 faces for the bottom
find areas of both
top=3*3+3*3+3*3+3*3=45
bottom one=3*10+3*3+3*3+3*10+3*10+3*(10-3)=129
add
45+129=174 mm^2
answer is B
volue
top shape is 3*3*3=27 mm^3
bottom is 10*3*3=90
add
27+90=117 mm^3
answer is C
6. 174 m^2 B
7. 117 mm^2 C
Usually the easiest way to solve this is by using a calculator. Of course only if your teacher allows you too.
