Hello :
y = 3x²+9x
= 3(x² + 3x )
= 3 ( x² +2(3/2)x +(3/2)²) -(3/2)²)
= 3((x+3/2)² -9/4)
y = 3 (x+3/2)² -27/4
<span>the x-coordinate of the vertex is : - 3/2</span>
Answer:
that's correct should give you brainliest
Well, you have to ask the question first.
1.5 is the area which makes it the diameter
Answer:
Incorrect measurement
Step-by-step explanation:
Given
Shape: Triangle
Length: 22in, 10in and 11in
Required: Determine if the measurements are correct
<em>For the measurement of a triangle to be true, the sum of any 2 sides must be greater than the length of the third side.</em>
<em></em>
i.e.
--- True
--- True
--- False
Since all three conditions are not true, then the measurements are incorrect
