Answer:
- √7
Step-by-step explanation:
√63 = √9*7 = √9*√7
Sqrt(9) = 3
3√7 - 4√7 = -1√7= -√7
Answer:
No x-intercept/Zero
Step-by-step explanation:
Substitute f (x)=0
Solve the equation
There is no x-intercept/zero
3x - 7
The perimeter is the sum of all 3 sides of the triangle
To find the third side subtract the sum of the 2 known sides from the perimeter
x + 3 + 2x + 4 = 3x + 7
third side = 6x - (3x + 7 ) = 6x - 3x - 7 = 3x - 7
