When a number x is added to it's square, the total is 12. find two possible values of x<br>​
Fudgin [204]

Answer:

<h2><u><em>x=3 or x=−4</em></u></h2>

Step-by-step explanation:

when a number x is added to it's square, the total is 12. find two possible values of x

x+x^2=12

x^2+x=12

x^2+x−12=12−12

x^2+x−12=0

(x−3)(x+4)=0

x−3=0 or x+4=0

x=3 or x=−4

x=3 or x=−4

He has 2yards of the string .He cut 5 /8 yards of the string for his project how much left
belka [17]
It would probably be 1 and 3/8 yards of string left because if he cut 5/8 yards of the string it would be a subject of subtraction, so if you would subtract that amount from 2 yards, the answer would be 1 and 3/8 yards of string left, hope this helps, good luck

Give the equation of the line passing through the point (20,2)that is perpendicular to y=−4x.
Cerrena [4.2K]

Answer:

y-2 = 1/4(x-20)  point slope form

y = 1/4x -3  slope intercept form

Step-by-step explanation:

y = -4x

The slope is -4

The slope that is perpendicular is the negative reciprocal

- (1/-4) = 1/4

The slope of our new line is 1/4

We have a point and the slope, so we can use point slope form

y-y1 = m(x-x1)

y-2 = 1/4(x-20)

If we want the line in slope intercept form, distribute

y-2 = 1/4x -5

Add 2 to each side

y-2+2 = 1/4x -5+2

y = 1/4x -3
