Answer:
x<5/2
Step-by-step explanation:
We have
2x−3<2
Add 3 to both sides.
2x−3 +3 <2 +3
which makes
2x<5
Divide both sides by 2.
2x/2 < 5/2
x<5/2
Answer: approximately 29 feet
Explanation: You need to find a tree so that the angle of elevation from the end of the shadow to top of the tree is 40 degrees.
The length of the shadow is an adjacent side and is 35.
The height of the tree is the opposite side. You could use X.
Tan ratio = opposite/adjacent
tan(40) = x/35
x = 35*tan(40) =29.37
Answer:
Your mom is annoying
Step-by-step explanation:
She keeps calling me even though its over.
You have to square the binomial.
(x^3 + 4y) (x^3 + 4y)
Using FOIL:
x^9 + 4(x^3)y + 4(x^3)y + 16y^2
x^9 + 8(x^3)y + 16y^2
You could also use the formula: (a+b)^2 = (a^2 + 2ab + b^2).
If you have 20/10, that equals 2. Then if you move the decimal place over 1 place then you have 2. If you divide 2 again by 10, then move the decimal place over in another place, it is equaling 0.2.
