Okay so you add 2 to both sides and then you multiple by 3 which will give you -y equals 18
Answer:
the length of its altitude is 34.64 cm
Step-by-step explanation:
Given;
length of a side of the equilateral triangle, L = 40 cm
All the sides of an equilateral triangle are equal
To get the altitude of the triangle, draw a perpendicular line from one of the vertices to intersect the opposite side.
Let the altitude = h
half of the opposite side intersected by the altitude = 20 cm
Apply Pythagoras theorem to determine the altitude 'h'
h² = 40² - 20²
h² = 1200
h = √1200
h = 34.64 cm
Therefore, the length of its altitude is 34.64 cm
F(x + 1) = 3(x + 1) + 4 = 3x + 7
Hopefully this helps
We are given with the expression 3/a - 9b = y and is asked to simplify the given equation. in this case, the first step is to multiply both terms with a. this results to 3 - 9 ab. = ay Since the two terms have different variables, this is the simplified form. the answer is <span>3 - 9 ab = ay </span>
Answer:
