Find the length of the third side of the right triangle. Give an exact answer and an approximation to three decimal places if needed. PLEASE HELP!!!!!!

Answer:

x = - 2

Step-by-step explanation:

x³-x²+ax+b = (x-1)(x-2)(x+c) = x³ + (c-3)x² + (2-3c)x +2c

c-3 = -1       C = 2

a = 2 - 3c = 2 - 3*2 = - 4

b = 2c = 4

third solution: x+2=0    x=-2

Answer:

x = - 2 ± [tex]\sqrt{11}[/tex]

Step-by-step explanation:

To solve the equation using the method of completing the square.

Given

x² + 4x - 7 = 0 ( add 7 to both sides )

x² + 4x = 7

add ( half the coefficient of the x- term )² to both sides

x² + 2(2) x + 4 = 7 + 4

(x + 2)² = 11 ( take the square root of both sides )

x + 2 = ± [tex]\sqrt{11}[/tex] ( subtract 2 from both sides )

x = - 2 ± [tex]\sqrt{11}[/tex] ← exact solution

Answer:

9 to the power of 4 is 36. Multiply to get the exact answer.

9³x2= 9 to the third power ° because if we have no callouts then that will be the ↑↓ estimate of the exponets.

Step-by-step explanation:

The answer is simple 36+36 (9³x2) x9 to the 8th. multiply and put in green box.

The probability that the coin Jan takes out is a dime would be 100% or 3/3

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

P(E) = Number of favorable outcomes / total number of outcomes

We are given that Jan has three dimes In her pocket and nothing else. she takes one coin out of her pocket.

Picking with replacement, twice from 3 dimes.

Probability of picking a dime each time = 3/3

Which is 100 percent because there is nothing els.

Answer:

x = 20, ∠ A = 125°

Step-by-step explanation:

∠ A and ∠ B are Alternate interior angles and are congruent, so

∠ A = ∠B , substitute values

6x + 5 = 4x + 45 ( subtract 4x from both sides )

2x + 5 = 45 ( subtract 5 from both sides )

2x = 40 ( divide both sides by 2 )

x = 20

Thus

∠ A = 6x + 5 = 6(20) + 5 = 120 + 5 = 125°

Answer:

∠A = 125 degrees.

Step-by-step explanation:

Graph both and find the corresponding points.

Answer:

a. -7, -8, -10

b. In -3x≥18, the solution set includes -6 (which gives -18) because -18 is equal to -18, which is allowed. In -3x>18, -6 is not allowed since -18 cannot equal -18.

Answer:

y=4x+(-9)

Step-by-step explanation:

Slope intercept form is y=mx+b

m is the slope which can be found using rise/run. In this case 4/1=4 so m=4

b is the y intercept which is the y value where the line passes through the X axis. This also can be found as the Y value where X=0 if that is easier for you. In this problem y=-9 where X=0. Therefore b=-9.

Plug these values back into the equation and you get the equation of the line in slope intercept form. For this line that is y=4x+(-9).
