Hey there!
1. To solve 9 x 5 , I could add the number 9 five times . . .
9 + 9 + 9 + 9 + 9 = 45
9 x 5 = 45 <----
2. I would use the same strategy as the first one, except add the number 8 five times . . .
8 + 8 + 8 + 8 + 8 = 40
8 x 5 = 40 <----
Hope this helps you.
Have a great day!
Answer:
-2x^2
Step-by-step explanation:
Simplify
x^-1 - 2x^2 - x^-1
becomes
-2x^2
Answer:
f(x) = -4x + 12
Step-by-step explanation:
y - 2x = -6x + 12
+2x +2x
f(x) = -4x + 12
Step-by-step explanation:
given,
the complete angle is complementry angle which is 90°
let the first angle be x and second angle be 7x ( as second angle is 7 times more than first angle )
now,
→ x + 7x = 90
→ 8x = 90
→ x = 90/8 = 11.25
therefore
1st angle = x = 11.25°
2nd angle = 7x = 7 × 11.25 = 78.75°
hope this answer helps you dear take care and may u have a great day ahead!
The first step of factoring is to try to factor out a common factor.
The terms x^2 and -9x have the factor x in common.
Factor out x from both terms.
x^2 - 9x = 0
x(x - 9) = 0
Now you have a product of fully factored terms equaling zero, so you can apply the zero product property to solve.
x = 0 or x - 9 = 0
x = 0 or x = 9
Answer: x = 0 or x = 9
