Answer:

factored form: (n + 4)²

Solving for n: n = -4

Step-by-step explanation:

n² + 8n + 16

To solve this, simplify. Note that the factors of n² & 16, when combined, must equal 8n. Find factors of 16:

Factors of 16:

1, 2, 4, 8, 16

Use the factor 4:

n² + 8n + 16

n 4

(n + 4)(n +4) = (n + 4)² is your factored form.

If you need to, solve for n. Take one of the parenthesis, and set it equal to 0:

(n + 4) = 0

Isolate the variable, n. Note the equal sign, what you do to one side, you do to the other. Subtract 4 from both sides:

n + 4 (-4) = 0 (-4)

n = 0 - 4

n = -4

Find two numbers that multiply to make the 1st number and add to make the 2nd number. Multiply -42; Add 1 _____, and _____

dedylja [7]

Answer:

-6 and 7

Step-by-step explanation:

It is useful to look at the factor pairs of -42.

-42 = -1(42) = -2(21) = -3(14) = -6(7)

Sums of these factor pairs are 41, 19, 11, 1.

You want the last pair of factors: -6 and 7.

the highest of three cylinders are 3 cm 9 cm and 5 cm if the cylinder has a capacity of 725 calculate the capacitance of the oth

Allushta [10]

The capacitance of the other cylinders are 2174. 94cm³ and 1208. 30cm³.

<h3>How to find the capacitance</h3>

Capacity of a cylinder is seen as its volume

Volume of a cylinder = πr²h

The heights of the cylinders are

a. 3cm

b. 9cm

c. 5cm

Let's find the radius

Capacity = 3. 142 × r² × 3

725 = 3. 142 × r² × 3

r² = $\frac{725}{3. 142 * 3}$

r² = $\frac{725}{9. 426}$

r² = 76. 91

r = √76. 91

r = 8. 77cm

Radius of the cylinders = 8. 77cm

For cylinder with height of 9cm

Capacitance = πr²h

Capacitance = 3. 142 × 8. 77 × 8. 77 × 9

Capacitance = 2174. 94 cm³

For cylinder with height of 5cm

Capacitance = 3. 142 × 8. 77 × 8. 77 × 5

Capacitance = 1208. 30 cm³

Thus, the capacitance of the other cylinders are 2174. 94cm³ and 1208. 30cm³.
