Solve for the value of x.

(r-5)(r+4)

(x+6)(x+2)

Step-by-step explanation:

1 r^2 - 1 r - 20

multiply the first and third terms

-20 times 1 equals -20. take the -1

*what are two numbers that multiply together that equals -20 but add to equal -1?

-5 times 4 equals -20

-5 plus 4 equals -1

(r-5)(r+4)

1 x^2 + 8 x + 12

multiply the first and third terms

12 times 1 equals 12. take the 8

*what are two numbers that multiply together that equals 12 but add to equal 8?

6 times 2 equals 12

6 plus 2 equals 8

=(x+6)(x+2)

Answer:

8 3/4 below sea level

Step-by-step explanation:

Given that:

Depth of fish at 7:00 A. M = 3 1/2 feets below sea level

Depth at 11:00a.m (4 hours later) = 5 1/4 feets below it's position at 7:00 a. M

Rational number to represent position of fish with respect to the water surface at 11:00 a. M

Position at 11:00 a. M :

Addition of the two depth distances given :

(3 1/2 + 5 1/4)

7/2 + 21/4 = (14 + 21) / 4 = 35 / 4

35/4 = 8 3/4 feets below sea level

Answer:

8.75, 8 3/4 or 35/4

Step-by-step explanation:

3 1/2 + 5 1/4

=(3+5) + (1/2 + 1/4)

=8 + (2/4 + 1/4)

=8 + 3/4= 8 3/4

=8 3/4= 35/4

Answer:

2x = 54

Step-by-step explanation:

The given information;

x = 3^3

solve

x = 27

(beacuse 3^3 = 3 * 3 * 3 = 27

find 2x:

2x = 2 * x

x= 27

2 * 27 = 54

2x = 54

The first choice is correct.

Answer:

Is this question in Spanish

Answer:

5.6 * 10^17.

Step-by-step explanation:

There are 17 digits after the 5 .

So it's 5.6 * 10^17.

Note that the first number must lie between 1 and 10.

I don't really understand which number we have to write in scientifc notation but I am assuming it is the number 560,000,000,000,000,000.

Ok so, 560,000,000,000,000,000 in scientific notation is 5.6 x 10^17.

This is because if you count the number of spaces behind the decimal point of 5.6 it is equal to 17. So, you would write the answer 5.6 x 10^17.

LOOK BELOW !!!

Step-by-step explanation:

[tex]7y = 8x - 14[/tex]

get rid of the Y and put in a 6

[tex]7(6) = 8x - 14[/tex]

[tex]7 \times 6 = 42[/tex]

[tex]42 = 8x - 14[/tex]

we need to get rid of the negative 14 so its only 8x.

to get rid of 14 on one side you add it to the other

[tex]42 + 14 = 56[/tex]

[tex]56 = 8x[/tex]

to get X by itself have to divide 8 by both sides

[tex]56 + \div 8 = 7[/tex]

[tex]8x \div 8 = x[/tex]

[tex]x = 7[/tex]

okay so I believe the answer is 30

step-by-step explanation:

So the area is length times width and a parallelogram is Bh so all you would have to do is multiply 10 by 30

Answer:

Between each black and white dot equals 1 unit because there are infinite dots, meaning that each dspace between the dots would equal 1 unit.

the answer to this is 2.38

Angle B = 56.309932474020215

This is through using a trigonometry calculator I forgot how to set it up tbh.

Hope this helps ;)

For extra info Angle C = 33.690067525979785.

They add up to 90 which added with the right angle of 90 means the interior angles add to 180 meaning it is in fact correct because a triangle is always 180 inside.

Answer:

A. ((a^2)b)((b^2)a)

Step-by-step explanation:

A. ((a^2)b) ((b^2)a)

Open parenthesis

(a^2b)(b^2a)

a^3b^3

B. (a^4)b^4−ab

a^4b^4 - ab

C. ((a^2b^2))/2ab

(a^2b^2) / 2ab

D. (ab)(ba) (ab)

(a^2b^2)(ba)

Therefore,

a^3b^3 = ((a^2)b) ((b^2)a)

Answer:

see explanation

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{opp}{20}[/tex] ( multiply both sides by 20 )

20 × tan40° = opp , thus

opp = 20 × 0.839 ≈ 16.78 , then

height of traffic light = 16,78 + 5 = 21.78 ft

------------------------------------------------------------------------

Using the tangent ratio in the right triangle

tan42.71° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{150}{d}[/tex] ( d is the distance between store and bank )

Multiply both sides by d

d × tan42.71° = 150 ( divide both sides by tan42.71° )

d = [tex]\frac{150}{tan42.71}[/tex] = [tex]\frac{150}{0.923}[/tex] = 162.5 m

Answer:

x = 3

Step-by-step explanation:

5x + 3 = 3x + 9

subtract 3 on both sides (cancels out 3) (inverse operation)

5x = 3x + 6

subtract 3x on both sides (cancels out 3x) (inverse operation)

2x = 6

divide both sides by 2 (isolates x) (simplifies)

x = 3

Answer:

The order of the angles of Δ ABC from smallest to biggest is

∠B < ∠C < ∠A ⇒ B

Step-by-step explanation:

There is a fact about a triangle

Let us use this fact to solve our question

In Δ ABC

∵ AB = 10 inches

∵ BC = 14 inches

∵ AC = 8 inches

→ Find the longest and shortest sides

∴ BC is the longest side

∴ AC is the shortest side

∵ BC is opposite to ∠A

∴ ∠A is the biggest angle in measure

∵ AC is opposite to ∠B

∴ ∠B is the smallest angle in measure

∴ The order of the angles of Δ ABC from smallest to biggest is

   ∠B < ∠C < ∠A
