You would take x^2-4x+3x-2=28
add common numbers x^2-x-2=28
set it equal to 0 x^2-x-30
use the quadratic formula x=1+-√1-4(1)(-30)÷2
Solve for x 1+-√131÷2
X÷≈6.223
plug x into both equations for kl and jl and you will get lenghts that are ≈13.829 for Jk and ≈16.669 for KL
Answer:
7 boxes
Step-by-step explanation:
Let x represent the amount of cookies that was brought to the party by Kendall
Each box contain 12 cookies
= 12 × x
= 12x
Kendall keeps 2 boxes for herself
= 12 × 2
= 24
Kendall has 60 cookies which she took to the party
Therefore the question can be represented as follows
12x = 24+60
12x= 84
Divide both sides by the coefficient of x which is 12
12x/12= 84/12
x= 7
Hence Kendall brought 7 boxes
2x+26+x+25=180
3x+51=180
3x=129
X=43
43+25
Answer
mZB=68
Okay so take away $20 from your $90 you get $70. Divide $70 by $5 per hour and you get to rent a surfboard for 14 hours.
Answer:
Three ways to find the slope of a line: You may have two points #(x_1,y_1)# and #(x_2,y_2)# (often one or both of these points may be intercepts of the #x# and/or #y# axes). The slope is given by the equation. #m=(y_2-y_1)/(x_2-x_1)#. You may have a linear equation that is either in the form or can be manipulated into the form. #y = mx + b#.
