→ Substitute cos 2x and sin 2x by their expressions
→ Subtract both sides by sin x
→ Take sin x as a common factor in the right side
From the graph, the equation has 4 solutions, the intersection points between the 2 graphs
X+3/x or 1/x^8(x-3). if “2-9 & 2-3x” are exponents then the 2nd anwser is the anwser if not then the first.
30 percent decrease
Step-by-step explanation:
looking at this i know its a percent decrease
so how do we find percent decrease ?
first we subtract the first value 39.39 & the final value 27.57
39.39-27.57 = 11.82
then we divide 11.82 by the first value
like this 11.82÷39.39 = 0.3000
then we multiply what we got by 100
0.3000×100= 30 percent
the way that most people mess up is when they divide sometimes they might do 39.39 divided by 11.82 instead of 11.82÷39.39.
Answer:
correct
Step-by-step explanation:
The perimeter is the sum of the sides.
Rectangle ( opposite sides are congruent ), thus
perimeter = 2x + 2(x + 18) = 2x + 2x + 36 = 4x + 36
Square ( sides are congruent ), thus
perimeter = 4(x + 9) = 4x + 36
The perimeters are the same, so the student is correct
Answer:
99 m
Step-by-step explanation:
The 10 covers required ...
(10 covers) × (3 m/cover) = 30 m
So the amount remaining is ...
150 m - 30 m - 21 m = 99 m
Lee has 99 m of the fabric left.
