Answer:

x³ + 11x² + 28x

Step-by-step explanation:

(x + 4)(x² + 7x)

Each term in the second factor is multiplied by each term in the forst factor, that is

x(x² + 7x) + 4(x² + 7x) ← distribute parenthesis

= x³ + 7x² + 4x² + 28x ← collect like terms

= x³ + 11x² + 28x

[tex] \huge \underline{ \sf \: Solution}[/tex]

[tex](x + 4)( {x}^{2} + 7x) \\ = x( {x}^{2} + 7x) + 4( {x}^{2} + 7x) \\ = {x}^{3} + {7x}^{2} + {4x}^{2} + 28x \\ = {x}^{3} + {11x}^{2} + 28x [/tex]

Answer:

perimeter would be 60ft

Step-by-step explanation

and square has 4 sides so you would multiply 4 by the square root of 225

Answer:

35.42%

Step-by-step explanation:

Answer:

C. 35.42%

Step-by-step explanation:

65 - 48 = 17

Since he grew 17 inches, you must figure out what percentage 17 is of 48.

17/48 = 1/100 (represents decimal)

Cross multiply: 17 ⋅ 100 = 1700 and 48 ⋅ 1 = 48

Divide: 1700/ 48

= 35.41666666666667

Round to the nearest hundredth:

= 35.42

Answer:

79.2 units

Step-by-step explanation:

Tangents to a circle from an external point are congruent , then

PQ = 27.4

QR = 5.9 + 12.2 = 18.1

PR = 12.2 + (27.4 - 5.9 ) = 12.2 + 21.5 = 33.7

Then

perimeter = PQ + QR + PR = 27.4 + 18.1 + 33.7 = 79.2

Answer:

$5820.07

Step-by-step explanation:

Substitute 243 into the equation for n:

[tex]c=117\sqrt[3]{243^{2} }+1264\\c=117\sqrt[3]{59049}+1264\\c=117*38.9407384+1264\\c=4556.06639+1264\\c=5820.06639[/tex]

Round 5820.06639 to the nearest hundredth:

5820.07

$5820.07

Answer:

38.42cm

Step-by-step explanation:

Given that the length of the sides of a rectangle are 30 cm and 24 cm.

The length of the diagonal can be obtiaed using Pythagoras rule

Length of the diagonal = hypotenus

Hypotenus = sqrt(opposite ² + adjacent ²)

Opposite and adjacent sides are 30cm and 24 cm

Hypotenus = sqrt(30² + 24²)

Hypotenus = sqrt(900 + 576)

Hypotenus = sqrt(1476)

Hypotenus = 38.419

Length of diagonal = 38.42cm

Answer:

find the size of angle O to the nearest degree

Answer:

68/99

Step-by-step explanation:

Answer:2800

Step-by-step explanation:

So 2 percent is 2/100 or 1/50 so just multiply 56 by 50 and you will get 2800

Answer:

40 kilometers

Step-by-step explanation:

the hypotenuse is a² + b² = c²

so first we have to get 32 and 24 into ²

            32² = 1024       (32 × 32)

            24² = 576         (24 × 24)

1024 + 576 = 1600

now we need to find the square root of 1600

√1600 = 40     (calculator)

therefore, the hypotenuse is 40 kilometers

goodluck, hope this helped,

Answer:

volume of Sphere B is 8 times greater than the volume of Sphere A

Step-by-step explanation:

Sphere A:  V = 4π (2^3)/3 = 32π/3

Sphere B:  V = 4π (4^3)/3 = 4π(64)/3 = 256π/3

volume of Sphere B / volume of Sphere A =  (256π/3)/(32π/3) = 8

Answer:

There are 3 boys for every 4 girls (3:4)

Step-by-step explanation:

3:4 is the simplest form of 24:32 and 6:8.

Therefore, there are 3 boys for every 4 girls.

Answer: height is 2

Step-by-step explanation:

A = 1/2bh

A = 3; b (base) = 3. Substitute these values in the formula and solve.

3 = 1/2*3*h = 3/2 h

h = 3 * (2/3) = 2

Answer:

Height = 2

Step-by-Step Explanation:

So, I'm not sure if "gh" is a measurement. But I'm thinking it should be solved like this.

Area =  3gh

Base = 3gh

Height = ?

Plug & Chug

3gh = 1/2 (3gh)(h)

2/1 · 3gh = 1/2 (3gh)(h) · 2/1

[tex]\frac{(2)(3gh)}{(3gh)\\}[/tex] = [tex]\frac{(3gh)(h)}{(3gh)}[/tex]

h = [tex]\frac{(2)(3gh)}{(3gh)}[/tex]

h = 2

Apologies if this is wrong, but I hope this helped!
