The length of a rectangle is 3cm more than the width. The area is 70cm^2. Find the dimensions of the rectangle​
Rom4ik [11]
Let width be x
Length would be x + 3
Area = L * W
Make an equation
(x) * (x+3) = 70
x^2 + 3x = 70
x^2 + 3x - 70 = 0
Quadratic formula
(-3 +/- rt 3^2 - 4 * 1 * (-70))/(2 * 1)
x1 = (-3 + 17)/2, x2 = (-3-17)/2
x = 7, x = -10
Dimension cannot be negative

Solution: width = 7
Length = 10

-9x +y =17 9x + 9y=19<br> solve for y equation 1
OLEGan [10]
Solution1: 9(x) + (y) = 17  

Solution 2: 9(x) + 9(y) = 19

Your graphic organizer ➡(y) - 9(x) = 17
9(y) + 9(x) = 19

(y) = 9(x) + 17(⬅Solution 1)

9(x) + 9(9)(x)+17 = 19 ;  90(x) = -134(⬅Solution 2)

(x) = -67÷45
= -1.48

  y = 18 ÷ 5
=3.6.

x-intercept ➡ -67/45

y-intercept: 18/5
⬆

y = 3.6; 18/5 (if that's what you're looking for)
