Answer:
36
Step-by-step explanation:
Given
x² + 12x
To make the polynomial a perfect square
add ( half the coefficient of the x- term)²
= x² + 12x + 6²
= x² + 12x + 36
= (x + 6)² ← a perfect square
Answer:
Meera is 10 years while her mom is 40 years
Step-by-step explanation:
Meera nother is 4 times as old as meera
After 5 her mum will be 3 times as old as her
The first step is to calculate Meera age
4x+5= 3(x+5)
4x +5= 3x+15
Collect the like terms
4x -3x= 15-5
x= 10
Meera mother age can be calculated as follows
= 4x
= 4×10
= 40
Hence Meera is 10 years and her mom is 40 years
Answer:
x = 135º
Step-by-step explanation:
Sum of angles in a triangle is 180
A = 180 - 66 - 69
A = 45º
--------------------
Supplementary angles total 180
x = 180 - 45
x = 135º
Answer:
A, slope
I am pretty sure it is the slope
