NEED CORRECT ANSWER PLEASE! THANKS:)

1 answer:

The answer is B. (2x + 5)(x + 1)You could answer this by expanding each answer until you found one that matched 2x^2 + 7x + 5, but I will only show how the answer expands:
2x × x = 2x^2
5 × x = 5x
2x × 1 = 2x
5 × 1 = 5

So in total those brackets expand to 2x^2 + 7x + 5. I hope this helps!

2(n+5)=-2 <br><br> I need the steps

Eva8 [605]

Answer:

n = -6

Step-by-step explanation:

2 ( n + 5 ) = -2

First, solve the brackets.

2n + 10 = -2

Now take 10 to the right side.

2n + 10 -10 = -2 - 10

2n = -12

Then divide both sides by 2.

$\frac{2n}{2} =\frac{-12}{2}$

And now you'll the value of n.

n = ( -6 )

Solve this linear system 28x + 44y = 964.40 21x + 33y = 723.30

Sladkaya [172]

28x + 44y = 964.40

21x + 33y = 723.30

Let's multiply the first equation by 4 and the second by -4

84x + 176y = 3857.6

-84x - 132y = -2893.2

Add the equations together.

0 + 44y = 964.4

Simplify

44y = 964.4

Divide both sides by 44

y = 964.4/44

Since we have the value of y, let's plug 964.4/44 into y for the first equation.

28x + 44(964.4/44) = 964.40

Simplify the left side

28x + 964.4 = 964.4

Subtract 964.4 from both sides

28x = 0

Divide both sides by 0

x = 0

In conclusion,

y = 964.4/44

x = 0

Usimov [2.4K]

Need additional information, which is the height and which is the diameter of the cylinder from the measurements supplied? Standard forumula for locating Radius and Volume of a cylinder are as follows.

Radius=Diameter/2
$rad=dia/2$

Volume=Base X height
$V=B*h$

Base= 3.14*r*r
