The equation that says the area is 40, 000 yards squared is 40,000 = (5x + 300)x
<h3>How to find area of a rectangle?</h3>
The area of a rectangle can be found as follows:
area of a rectangle = lw
where
Therefore, the equation that says the area of the yard is 40, 000 yards squared is as follows:
l = length = 5x + 300
w = width = x
Therefore,
area = (5x + 300)x
40,000 = (5x + 300)x

Answer:
70 = 1/2 b *8
17.5 inches =b
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
We know the area and the height
70 = 1/2 b *8
70 = 4b
Divide each side by 4
70/4 = 4b/4
17.5 =b
Answer: The primary cause of low pH in precipitation over northeastern North America is sulphuric acid (H2SO4) from industrial and urban emissions of sulphur dioxide (SO2). Nitric acid (HNO3) generated from emissions of nitrogen oxides (NOx) is a significant contributing factor in this region.
Step-by-step explanation:
Answer:
1. Take a=4, b=6
a+b
=4+6
=10( Both are positive integers)
2. a=4 , b= -6
then 4 + (- 6)
= 4 - 6
= -2 [Smaller is positive integer and larger is negative integer , So subtract smaller from larger and apply the sign possessed by larger integer]
3. a = -4, b= -6
a+ b
= -4 -6
=-10 [ Both are negative integers add them apply - sign before the number.]
4. a = -4, b=6
a +b
= -4+ 6
= 2 [one is positive and other is negative subtract smaller from larger and apply positive sign before the number.]
