Answer:
The solutions are the points (-3,0) and (-1,-2)
Step-by-step explanation:
we have
-----> equation A
-----> equation B
Solve the system of equations by graphing
The solution of the system of equations are the intersection points both graphs
The solutions are the points (-3,0) and (-1,-2)
see the attached figure
1/4 c + 3d
c=6 d=7
1/4 (6) + 3(7)
1.5+ 3(7)
1.5+ 21
22.5
Since we have the length and width of the window, we can multiply the two values.
Convert both fractions to improper fractions
(26/3)*(23/4)
=598/12 ft squared
= This simplifies to 49 5/6 ft. squared
Answer:
Length=17
Width=4
Step-by-step explanation:
Length=x
Width=2x-30
x(2x-30)=68
2x²-30x=68
2x²-30x-68=0
2(x²-15x-34)=0
2(x+2)(x-17)=0
So x equals either 17 or -2. Since it can’t be -2, x=17
Length=x=17
Width=2x-30=2*17-30=34-30=4
