This is all I got if I got it right. Is this one of your answers?
Answer:
Step-by-step explanation:
Perimeter = 4c + 9 + 7c - 5 + 5c + 2 + 5c - 3
= 4c +7c + 5c +5c + 9 - 5 + 2 - 3
= 21c + 3
Step-by-step explanation:
your don't see what went wrong ?
Tyrell worked on
16 - 2(4 + 3x)
what do brackets mean ? they mean that this operation has to be done before everything else in the expression.
as this contains a variable, we cannot fully calculate it, true, but we need to keep this in mind and always treat the content of the brackets as one package.
so, whatever I do from the outside with one part of that package, I have to do also with all the other parts of that package.
so, the multiplication with -2 has to happen with both : 4 and 3x. not just with 4.
therefore, the correct simplification looks like
16 - 8 - 6x
8 - 6x or -6x + 8
Amelia multiplied correctly, but then made a mistake summing things up
10x - 3(4x + 1)
10x - 12x - 3
10x - 12x = -2x
I can't mix the pure constant -3 into the factors of x. that would be like the famous mixing of apples and oranges.
so, the result is
-2x - 3
Answer:
The area of the rectangle is 0.0875 sq ft.
Step-by-step explanation:
Given that,
The length of the rectangle, L = 0.35 feet
The breadth of the rectangle, B = 1/4 feet
We need to find the area of the rectangle. The formula for the area of a rectangle is given by :
A = LB
Put all the values,
So, the area of the rectangle is 0.0875 sq feet.
Your answer would be 288. Also, did you mean 8/9? Hope I helped!
