but after long hard thinking the answer is
length =53.99344 feeeet!!
width = 50.99344 feeeet!!
Or
length = 16.4572 meters!!
width = 15.5428 meters!!!

What is a number system?
The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.
Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.
The additive inverse of an number is a number by which addition the resultant becomes zero.
For example, the additive inverse of 3 is -3
Now,
The additive inverse of -4 will be 4 which is positive, not negative.
The additive inverse of 0 is 0 which is not negative.
Hence "The additive inverse of a number is not always negative".

No it isn’t
In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. ... For a real number, it reverses its sign: the opposite to a positive number is negative, and the opposite to a negative number is positive. Zero is the additive inverse of itself.

Answer:
5.66038
Step-by-step explanation:
Given
Mean= μ=100
SD= σ=5.3
Z-score of 130= ?
The z-score of any value tells us that how many standard deviations that value is from the average or mean.
The Z-score of any data value is found by subtracting the mean from it and then dividing by the standard deviation.
z-score= (x- μ)/σ
z-score of 130= (130-100)/5.3
=30/5.3
=5.66038

x% of 90 is 50
In math
"of" means multiply
"is" means equals
x% of 90 is 50 means
x% x 90 = 50
90x = 50
x = 50/90
x = .5555
Multiply by 100 to convert to percent (move decimal 2 places to the right)
.5555 = 55.55% = 55.6% rounded to the nearest tenth
Lets keep n as the percentage
90 and 90 cancels out
100 and 100 cancels out
n = 55.55..% ≈ 55.6%

1)Let's call A=inter (4x-y-7=0, x+3y-31=0)
4x-y=7
x+3y=31
==>13x=52==>x=4
and y=4*4-7=9
A=(4;9)
2)Let's call B=inter (4x-y-7=0, x+5y-7=0)
4x-y=7
x+5y=7
==>21x=42
==>x=2 and y=4*2-7=1
B=(2,1)
3) Slope of BD: y=-x/3+31/3 ==> slope perpendicular=3
Line BD:y-1=3(x-2)==>y=3x+5
4) Slope AE: y=-x/5+7/5 ==>slope perpendicular=5
Line AE: y-9=5(x-4)==> y=5x-11
5) intersection (BD;AE):
y=5x-11
y=3x-5
==>2x=6==>x=3
and y=3*3-5=4
H=(3,4)
