Answer:
Since this is a multi-part question, just look at the bolded parts under each letter. I hope this helps a bit ;)
Step-by-step explanation:
A)
All sides of a square are congruent. "s" represents the square's perimeter:
s=4x.
"r" is the rectangle's perimeter:
r= 4x+26
since the perimeter = 2W + 2L:
2W + 2L= 4x+ 26
and W=x, so:
2x + 2L= 4x + 26
Subtract from both sides:
2L= 2x +26
Divide both sides:
the length of the rectangle "L"= x +13.
B) Plug 5 into the equations:
L= 5+ 13 or 18.
2(18) + 2(5)= r
36+ 10 = r or 46
s= s+ 26
s= 46-26 or 20.
20/4= 5...
It seems (at least to me, feel free to give constructive criticism) that the only logical conclusion is that 5 <u>could</u> be the value of x.
C) You would likely need to use substitution to solve, but unless I am much mistaken, this looks like an infinite-solutions equation.
L=w+13
Answer:
y = -3x - 1
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
Substitute the given values, -3 = m and -1 = b.
Answer:
D&B
Step-by-step explanation:
turn 6 to a fraction which is 6/1
So you keep the first fraction the same
change the division sign to a multiplication sign
change 3/4 to 4/3
so 6/1x4/3
multiply straight across the top and bottom
you get 24/3
simplified is 1/8lbs
The answer is b. Hope this was helpful
