8x10 = 80
4x4 = 16
2x4 divided 2 = 4
80+16+ 4 = 100
Answer:
no one of them has to be 90 degrees
Step-by-step explanation:
Answer:
The number -100 is a rational number and an integer
Answer:
15.5
Step-by-step explanation:
16.5-10
=15.5
So 15.5 is the range
x² - 14x + 46 = 0
subtract 46 from both-side
x² - 14x = -46
Add the square of the half of the co-efficient of x
x² - 14x + (-7)² = -46 + 7²
(x-7)² = -46 + 49
(x-7)² =3
Take the square root of both-side
x-7 = ±√3
x-7= ±1.732
Add 7 to both-side of the equation.
x= 7 ± 1.732
Eithe x= 7 + 1.732 or x= 7 - 1.732
x=8.732 or x=5.268
Therefore x = 8.732 , 5.268
