3/4(5)+3y=12
15/4+3y=12
3y=12-15/4
3y=33/4
y=33/4 /3
y=11/4
Combine the like terms
(4x^2 + 2x^2) +(7x - 5x) + (3 - 8)
6x^2 2x -5
6x^2 + 2x - 5
Answer is A
Answer:
b
Step-by-step explanation:
first, group the terms with the same power together and it would become (-9n⁵-4n⁵)+(n³-9n³)+(11n+6n). then, combine the terms in each group together which would get -13n⁵-8n³+17n as the answer
Answer:
<h2>a. It should look for 3 linear factors.</h2><h2>b. There are 3 dimensions.</h2><h2>c. x = 1.7</h2><h2>d. Maximum value is 12.597</h2>
Step-by-step explanation:
a.
=
=
= 
Hence the factorized form of the volume of the poly is 
3 linear factors should needed to be look for.
b.
The 3 dimensions are (x + 4), x, (x + 3).
c.
Let, f(x) = 
Now,
= 
Let
=
and
=
= 
The value will be maximum, if f1(x) = 0 and f2(x) < 0.
\\
\\ 
x = 1.69 ≅ 1.7 or x = -2.36 ≅ -2.4
Now f2(1.7) < 0.
At x = 1.7, the volume will be maximum.
d.
The maximum value is f(1.7) = 12.597(approximately)
Y= -16/7x + 23/14
