Choose an equation that would be used to solve 0 = -x2 + 10x – 8
Answer: (x-5)^2=17
Answer:105
Step-by-step explanation:
becasue you can mutiply 35 3 times and 21 5 times and you get the same number as 105
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
• tan x = 
• sec x = 
, csc x = 
Consider the left side with x = Θ
=
= 
× 
= 
= ×
= secxcscx = right side ⇒ verified
Answer:
x² + 5x + 6
Step-by-step explanation:
Foil means first, outside, inside, last
First: (x+2)(x+3)
x × x = x²
Inside: (x+2)(x+3)
x × 3 = 3x
Ouside: (x+2)(x+3)
2 × x = 2x
Last: (x+2)(x+3)
2 × 3 = 6
adding them together:
x² + 3x + 2x + 6 = x² + 5x + 6
