Do the rainbow method
x^2 - 6x + 2x - 12
Now simplify
x^2 - 4x - 12
The answer is x^2-4x-12
Answer:
t 24
Step-by-step explanation:
we can add 5 to both sides
-t/6 -4
multiply both sides by 6
-t -24
divide by -1, when dividing by a negative, the inequality flips
t 24
Answer:
57 units²
Step-by-step explanation:
Let the radius be r
r² + r² = 10²
2r² = 100
r² = 50
r = 5sqrt(2)
Shaded area:
Circle - Square
pi×r² - 10²
pi(50) - 100
50pi - 100
50(3.14) - 100
57
3,10,5 CANNOT be a triangle as 3+5 IS NOT greater than or equal to 10
10,8,5 CAN be a triangle as 8+5 is greater than or equal to 10
a simple way to figure out if three lengths can be a triangle is to take the two smaller numbers and see if they are greater than or equal to the larger number.
