Answer:
length = 24 meters
Step-by-step explanation:
1. l = 2w
2. P = 2l + 2w
P=72
3. 72 = 2l + 2w
4. Substitute w=l/2 to solve for l
72 = 2l + 2(l/2) ---> 72 = 3L - Divide by 3 on both sides
L= 24 meters
Answer:
The function graphed is f(x) = 3x + 1
See that the y=intercept is at (0,1). That's where the +1 comes from.
Note that the graph goes up 3 spaces every time it goes 1 to the right. 3/1 = 3 is the slope.
The answer to 12 is C.
The answer to 13 is B. Neither is a function. For a function of x to exist, for every x, there must be only one y. In both tables, there's a number for x that gives two different y's.
Step-by-step explanation:
Solve your equation step-by-step.
2s+s+12=132
Simplify both sides of the equation.
2s+s+12=132
Simplify:
3s+12=132
Subtract 12 from both sides.
3s+12−12=132−12
3s=120
Divide both sides by 3.
3s/3 = 120/3
s=40
x,x+2,x+4 the answer here is how i got it =x+x+2+x+4=180
=3x=174
=x=58
x=58
x+2=58+2=60
x+4=58+4=62
7 because 15-8 = 7, so the answer is 7
