Answer:
2α^2+15α+21
Step-by-step explanation:
(5α+α²-14) + (10α +α²+ 35)
Combine like terms
α^2+α^2+5α+10α-14+35
2α^2+15α+21
Answer:
Equation: y=7x
y=-28
Step-by-step explanation:
y=kx
y=98
x=14
98=14k
98/14=7
k=7
Equation: y=7x
x=-4
y=7•-4
y=-28
Answer:
75 in²
Step-by-step explanation:
(see attached for reference)
recall that the formula for area of a circle is given by
Area = π r²
where
π = given to be 3
r = radius given as 5 in
simply substituting the values into the equation:
Area = π r²
= 3 x 5²
= 3 x 25
= 75 in²
Tripled
original volume 3*6*10=180
when one is tripled 3(3) * 6*10 = 3*3*6*10=180*3
it doesnt matter which is tripled
