first step to remove brackets
here write them in serial order,
=5x²+3x+4+5x²+5x-1
=5x²+5x²+3x+5x+4-1
=10x²+8x-3
Answer:
65
Step-by-step explanation:
Angle A is 55 degrees.
A triangle adds up to 180 in degrees so 60 + 55 = 115
180 - 115 = 65 therefore angle C is 65 degrees.
Angle B is equal to angle C so it's also 65 degrees.
Basically:
A - 55
B - 65
C - 65
6 and 3/4 divided by 1/2
27/4 divided by 1/2
27/4 * 2/1 = 27/2 = 13 and 1/2
its b because if you multiply 3 x 6 you get 18 which is outside the radical
Answer:
b
