Answer:
the perimeter is simply 2L + 2W
So lengthy 8.3
2(8.3) + 2(w) =22.4
16.6=2(w) =22.4
2(w) = 5.8
w = 5.8 divide by 2
The width is 2.9
Answer:

Step-by-step explanation:
Use the general formula of exponential equation

Plug 0,2 into the function








B=0.5

He will need 2 more months to reach up 7 centimeters.
4 cm are long and 1.5 cm grows per month.
in 2 moths her hair will grow 3 inches=4+3=7
2x≤7
where x=1.5 cm

69
Step-by-step explanation:
Answer:
I gave you most of the answer. I'll let you check my work and find the point using the solution.
Step-by-step explanation:
The first thing we do is we divide by negative one in the first equation to get
y = -x.
-3x + 3y = -36
Plug in y = -x and get
-3x + 3(-x) = -36
= -3x - 3x = -36
This equals -6x = -36
divide both sides by -6 and you get 6. 6 is your x value
Plug 6 back in to the second equation.
-3x + 3y = -36
-3(6) + 3y = -36
-18 + 3y = -36
3y = -18
y = -6
