A=wl is the area of the rectangle but here’s a picture to show u this might help u with the length and width have a wonderful and nice day
Use the equations:
17 = D + N+ Q
D=N/3
Q=N+3
Then Substitute D and Q
17 = (N/3)+N+N+3
Solve for N; N=6; then substitute N for D=N/3 and Q=N+3
The answer is
Q=9
D=2
N=6
Answer:
D: 5
E: -2x
F: x^1
Step-by-step explanation:
4*5=20
-14x/7=-2x
x^3/x^2=x^1
the last one may not be write but I think that they are all correct
Answer
let the first number be x
second number be y
5*(x)+y=-21---------->equation 1
2*(x)+y=-9------------->equation2
<h2>
eq1 * 2:</h2>
2(5x+y)=2*-21
10x+2y=-42
<h2>
eq2 * 5:</h2>
10x+5y=-45
10x+2y=-42
-(10x+5y=-45)
-----------------
0 - 3y=3
y=3/-3
<h2>
y=-1</h2><h3>
sub y=-1 in eq1;</h3><h3>
5x+y=-21</h3><h3>
5x+ -1=-21</h3><h3>
5x-1=-21</h3><h3>
5x=-21+1</h3><h3>
5x=20</h3><h3>
x=20/5</h3><h2>
x=4</h2><h2>
y=-1</h2>
