Answer:
a²+9a+18
Step-by-step explanation:
axa+ax3+6xa+6x3
An equilateral triangle is a triangle in which all three sides have the same length
⭆ 14 = 3x - 4
⭆ 3x = 14 + 4
⭆ 3x = 18
⭆ x = 18/3
⭆ x = 6
In equilateral triangle, all three internal angles are also same and each are of 60°.
⭆ 5y - 5 = 60
⭆ 5y = 60 + 5
⭆ 5y = 65
⭆ y = 65/5
⭆ y = 13

Answer:The answer for number 3 is 240
Step-by-step explanation:
Answer:
A system of equations that represents the situation is:
3x + 2y = 315..... Equation 1
2x + 4y = 450...... Equation 2
Step-by-step explanation:
Let the number of
Haircuts = x
Hair dyes = y
Hence:
Alexandra finds that she can give:
3 haircuts and 2 hair dyes in 315 minutes.
3x + 2y = 315..... Equation 1
Giving 2 haircuts and 4 hair dyes takes 450 minutes
2x + 4y = 450...... Equation 2
Therefore:
a system of equations that represents the situation is:
3x + 2y = 315..... Equation 1
2x + 4y = 450...... Equation 2
