Let's assume that the Length of the rectangle is (2x-5)m and The breadth of the rectangle is (2x+60)m.
Now, note that to find the perimeter of a shape requires the sum of all of its sides. In this case, A rectangle has 2 Lengths and 2 Breadths. Thus, the perimeter of the rectangle is
2(2x-5)+2(2x+60)=( 4x-10)+ (4x+120)
= 8x+110
We don't stop there, the question says if the value if x is 12m
So, we substitute X into 12
8(12)+110= 96+110
=206
The correct answer is B. (7,2)
Answer:
$21
Step-by-step explanation:
-11.00 + 44.50 = 35.50
35.50 - (6.25 * 2) = 21.00
Answer: [D] -16x^4y + 4xy^4 + 16xy
Remove parentheses: <u>(-a) = -a</u>
-3xy^4 - 7x^4y + 7xy - 9x^4y + 9xy + 7xy^4
Group like terms
-7x^4y - 9x^4y - 3xy^4 + 7xy^4 + 7xy + 9xy
Add similar elements: <u>-7x^4y - 9x^4y = -16x^4y</u>
= -16x^4y - 3xy^4 - 7xy^4 - 16xy
Add similar elements: <u>-3xy^4 + 7xy^4 = 4xy^4</u>
= -16x^4y + 4xy^4 + 16xy
