Answer:
x=8
Step-by-step explanation:
if you multiply 6 by 8 and subtracted by 3 it will equal 45
2980 round everything to the nearest tens and add with your head to get it
Angle 4: 98
Angle 3: 82
Angle 2: 98
This is true because 180-82 =98 meaning angle 2 and 4 are 98 leaving angle 3 to be 82
Hope this helps
Answer:
third option
Step-by-step explanation:
Given
f(x) = 40x + 5x² ← express in standard form
f(x) = 5x² + 40x ← factor out 5 from each term
f(x) = 5(x² + 8x)
To complete the square
add/ subtract ( half the coefficient of the x- term)² to x² + 8x
f(x) = 5(x² + 2(4)x + 16 - 16)
f(x) = 5(x + 4)² + 5(- 16)
f(x) = 5(x + 4)² - 80
