Answer:

5a(a + 2)

Step-by-step explanation:

Given

(3a + 1)² - 4a² + 4a - 1 ← expand factor using FOIL

= 9a² + 6a + 1 - 4a² + 4a - 1 ← collect like terms

= 5a² + 10a ← factor out 5a from each term

= 5a(a + 2)

Answer:

Step-by-step explanation:

The coefficient is the initial amount: $15.35.

The growth factor is the base of the exponential term: 1.0279. The growth rate is 1 less than this: 1.0279 -1 = 0.0279 = 2.79%. It is positive, so represents a growth of 2.79% per day.

The radius of the inflated beach ball is equal to 58 inches.

Surface Area of a Sphere. A = 4 π r². The volume of a Sphere. V = (4 ⁄ 3) π r³. Where r is the radius of the circle.

Given: The volume of the sphere is 14,310 inches³

we know the volume of the sphere is  4/3 πr³

Thus equating we get

4/3 × 3.14×r³=14310

r³=3417.99

r³=3418

r=58.463 or 58 (approx)

Answer:

6x+2

Step-by-step explanation:

The perimeter is all of the sides added together.

We know that in a rectangle, sides that are parallel to each other are the same.

So, to find the expression that represents the perimeter, you have to multiply 2x+1 by 2 and x by 2 and add both of those together.

(2*(2x+1))+(2*(x))

(4x+2)+(2x)

4x+2+2x

Answer:

the solution is : (2 , 3)

Step-by-step explanation:

hello :  here is an solution

3x + 2y=12.....(*)

y=2x -1​.....(**)

put the value for y  in (*) :

3x + 2(2x-1)=12

3x+4x-2 = 12

7x =14

so : x =2

but : y=2x -1

y =2(2)-1 = 3

Answer:

x ≈ 14.6

Step-by-step explanation:

Using the sine ratio in the right triangle

sin59° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{17}[/tex] ( multiply both sides by 17 )

17 × sin59° = x , then

x ≈ 14.6 ( to 1 dec. place )

Answer:

Step-by-step explanation:

let x be the population

so we have ,

2x= 6h

?= 3 days or 3×24h

by cross multiplication we have

2x× 72h= 6h×?

?= 2x×72/6 = 24x

So, in three days the bacteria will b 24 times current population.

Answer:

The volume of the cylinder is 367.6 M^3

Step-by-step explanation:

Mathematically, we have the volume of a cylinder calculated as follows;

V = pi * r^2 * h

r is the base radius given as 3 m

h is the height given as 13 m

So, we have the volume as;

V = 22/7 * 3^2 * 13 = 367.6 M^3

Answer:

367.6 m³

Step-by-step explanation:

h=13       r=3                              identify variables

V= πr² h                                  use volume of a cylinder formula

V=π(3)²(13)                            substitute variables into formula

V= 367.56634047                   multiply

V=367.6 m³                            round to the nearest tenths place

Answer:

8 hours

Step-by-step explanation:

Answer:

21 hours

Step-by-step explanation:

8 evenings x $2 per evening = $16

$121 - $16 = $105

$105 / $5 per hour = 21 hours

to check:

21 hours x $5 per hour = $105

8 evenings x $2 per evening = $16

$105 + $16 = $121

Answer:

15/8 cup or [tex]1\frac{7}{8}[/tex] cup

Step-by-step explanation:

3/4 = 0.75

Ratios:

[tex]\frac{0.75}{12} =\frac{x}{30} \\\\12x=22.5\\x= 15/8[/tex]

Answer:

[tex]\frac{15}{8}[/tex] cup

This can also be expressed as the following:

[tex]1\frac{7}{8}[/tex] cup

Step-by-step explanation:

This problem involved ratios. A ratio is a way of expressing one value compared to another when the two values being compared are of a different unit. The problem gives one the general ratio of the following,

[tex]sauce (cups) : people (number)[/tex]

Substitute in the given values, since one knows the units, it is unnecessary to write it,

[tex]\frac{3}{4}:12[/tex]

In this problem, the ratio of cups of sauce to people is constant, therefore one can say that the amount of sauce that (12) people need is proportional to the amount of sauce that (30) people need. Thus, set up an equation to solve for the unknown amount of sauce that (30) people need. Let parameter (x) represent the unknown amount of sauce.

[tex]\frac{3}{4} : 12 = x : 30[/tex]

Use cross products to simplify,

[tex](12)(x)=(\frac{3}{4})(30)[/tex]

Simplify,

[tex]12x=\frac{45}{2}[/tex]

Inverse operations,

[tex]12x = \frac{45}{2}[/tex]

Multiply both sides by (2)

[tex]24x=45[/tex]

Divide both sides by (24),

[tex]x=\frac{45}{24}[/tex]

Simplify,

[tex]x=\frac{15}{8}[/tex]
