(7 + 7)² = 14² = 196
(7 + 6)² = 13² = 169
196 > 169
Therefore (7 + 7)² > (7 + 6)²
Could've deducted without the math but might as well show the work.
20=-5-x
25=-x
-25=x
First, parentheses, distribute the negative
Then, add 5 to both sides
And finally, divide by -1 which give you the answer -25
Answer: 5/6
WORKINGS
The denominator of 3/4 is 4
The fraction we are to write has a denominator of 6
Lowest common multiple of 4 and 6 is 12
Therefore, we have to re-write 3/4 with 12 as the denominator
Multiply both numerator and denominator of 3/4 by 33/4 = 9/12
Since 1 = 12/12
The fractions are less than 1, but greater than 3/4 are therefore, 10/12 and
11/12
Reduce both numbers to their lowest factor
10/12 = 5/6
11/12 cannot be further reduced
Therefore, the fraction less than 1 with denominator of 6 that is greater than 3/4 is 5/6
268.50 rounding to the nearest tenth means the closest even number so that would make this 268.50

Answer:
B) 37.947
Step-by-step explanation:
Using the given formula, we find ...
s = (12 +11 +7)/2 = 15
A = √(15(15 -12)(15 -11)(15 -7)) = √1440 = 12√10 ≈ 37.947 . . . square yards
