Answer:
ITS 280
Step-by-step explanation:
Rounding - when you solve
27.8 x 9.6 = 266.88
thats nearest to 280
:) Have a great day
Answer:
59 yards x 99 yards
Step-by-step explanation:
Soccer fields are rectangular. If the width is W and the length is L:
316 = 2W + 2L
5841 = WL
We have two equations and two variables. Start by solving for one of the variables in the first equation:
316 = 2W + 2L
158 = W + L
W = 158 − L
Substitute into the second equation
5841 = (158 − L) L
5841 = 158 L − L²
L² − 158 L + 5841 = 0
Factor (or use quadratic formula):
(L − 59) (L − 99) = 0
L = 59 or 99
Find W:
W = 99 or 59
Therefore, the dimensions of the soccer field are 59 yards by 99 yards.

Option A: -24 is the coefficient of i
Explanation:
The expression is
To determine the coefficient of i, first we shall find the square of the binomial for the expression
The formula to find the square of the binomial for this expression is given by
where and
Substituting this value and expanding, we get,
Simplifying the terms, we have,
Thus, from the above expression the coefficient of i is determined as -24.
Hence, Option A is the correct answer.
