Answer:
V(cylinder) = πr²h
h=3 cm
r=2 cm
V(cylinder) = πr²h = π*2²*3 =12π cm³
Answer : 12π cm³.
Answer:
4x+11
Step-by-step explanation:
Assuming you mean g(x)=-6X-7
f(x)-g(x)
Replace f(x) with-2x+4 and g(x) with -6x-7
-2x+4 - (-6x-7)
Distribute the minus sign
-2x+4+6x+7
Combine like terms
-2x+6x+4+7
4x+11
Answer: There are 18 students in a van and 24 students in a bus.
Step-by-step explanation:
Let the number of students in the van be 'x' and the number of students in bus be 'y'.
Then, According to the question, we have the following system
Multiply 2 to both the sides of equation (2), we get
Subtract equation (1) from equation (3), we get
Substitute value of x in (1), we get
Hence, there are 18 students in a van and 24 students in a bus.
Answer:
−10x + 4.35xy + 55y + 9.58
Step-by-step explanation:
Step 1: Collect like terms.
(6x − 16x) + 4.35xy + (16y + 39y) + 9.58
Step 2: Simplify and you're done!
−10x + 4.35xy + 55y + 9.58
for number 7. it would be 3 which is a would be 3 greater than 2
