The factored expression ofx^3 - 7x^2 -5x +35 is (x^2 - 5)(x - 7)

<h3>What is an expression?</h3>

An expression is an algebraic term used for a mathematical statement that includes addition subtraction multiplication and division

x^3 – 7x^2 – 5x + 35

factor the given equation

x^2(x – 7) – 5(x - 7)

Factor out x - 7

(x^2 - 5)(x - 7)

Therefore, the factored expression is (x^2 - 5)(x - 7)

$Use:\\\\i=\sqrt{-1}\to i^2=-1\\\\a^2-b^2=(a-b)(a+b)\\--------------------\\\\4x^2+81=2^2x^2+9^2=(2x)^2-(-9^2)=(2x)^2-(-1)(9^2)\\\\=(2x)^2-(i^2)(9^2)=(2x)^2-(9i)^2=\boxed{(2x-9i)(2x+9i)}$

A baseball stadium holds 15,002 seats. The lower level has 50 fewer than three times as many seats as the upper

Elanso [62]

Answer:

B) The equation x + (2 x + 40) + (3 x - 50) = 15,002 represents this scenario suitable.

Step-by-step explanation:

Let x represent the number of upper-level seats.

Total seats in stadium = 15,002

Now, seats in the lower level = 3 ( Seats in upper level ) - 50

= 3x - 50

or, the total seats in the lower level = (3 x - 50)

Also, seats in the middle level = 2 ( Seats in upper level ) + 40

= 2x + 40

or, the total seats in the middle level = (2 x + 40)

Now, according to question

Upper Level seats + Middle level seats + Lower level = Total seats

⇒ (x) + (2 x + 40) + (3 x - 50) = 15,002 seats

Hence, the equation x + (2 x + 40) + (3 x - 50) = 15,002 represents this scenario suitable.

The measure of an angle is seven times the measure of its supplementary angle. What is the measure of each angle?

MrMuchimi

Step-by-step explanation:

7x= 180-x

7x+x= 180

8x= 180

x= 22.5

the angle is 22.5

its supplementary angle is 157.5

In the first semester, Jonas took seven tests in his math class. His scores were: 88 81 94 84 100 94 96.

maksim [4K]

The median is the middle-most number. First we need to put the numbers in order from lowest to highest:

81 84 88 94 94 96

The easiest way to find the median is to cross out the first and last number and then continue until you reach the middle.

So cross out 81 and 96:
84 88 94 94 are left.

Cross out 84 and 94:
88 and 94 are left.

Since we are left with 2 different numbers, we need to find the average of them and that’s our median. (88 + 94)/2 = 91

91 is the median.
