Answer:
A= 15 root 5 - 10 ÷ 41
Multiply (3 root 5 - 2) top and bottom. Simplify
B= - 2
Multiply (root 3 + root 5) top and bottom. Simplify
C= 6x - 3 root xy ÷ 4x - y
or
3x - 3 root xy ÷ 2x - y
(because 6 & 4 is Divisible by 2)
Multiply (2 root x - root y) top and bottom. Simplify
Root means a square root - so, replace the word root with a square root!
Hope this helps!
The little lines through the two sides mean they are the same length.
When the two sides are the same length the 2 corresponding angles are also the same, so Angle A and Angle B are both 34 degrees.
The three inside angles of a triangle equal 180, so angle C = 180 - 68 = 112
Angle C is given as 4y, so 4y = 112
Divide both sides by 4:
y = 112 / 4
y = 28
Answer: f(3) = 23
Step-by-step explanation:
Put 3 where x is in the expression for f(x) and do the arithmetic.
... f(3) = 2·3^2 +5√(3-2)
... f(3) = 18 + 5 = 23
