Answer:
One solution
Step-by-step explanation:
Basicly its just seeing if x can be anything, nothing or one thing so x · 0 = 0 has infinite answers, 4x + 6 = 11 has one solution, and 0x = 5 has no solution
Answer:0.2588
Step-by-step explanation:
To find the exact value for
Sinpi/12
pi=180°
So
Sin 180/12
Sin15°
=0.2588
Answer:
1. It has two points in common with the x-axis.
2. The vertex in relation to the x-axis is at 
Step-by-step explanation:
The points that the equation has in common with the x-axis are the points of intersection of the parabola with the x-axis.
To find them, substitute y=0 and solve for "x":

Use the Quadratic formula:

It has two points in common with the x-axis.
To find the vertex in relation to the x-axis, use the formula:

Substituting values, you get:

Answer:
D. 49p² - 64
Step-by-step explanation:
(7p - 8)(7p + 8)
Solving this requires the 'difference of squares' concept which states;
If (a - b)(a + b)
Then the solution must be a² - b²
Considering (7p - 8)(7p + 8) then the answer is;
(7p)² - 8² = 49p² - 64
2/3 because it’s out of 3, if you cut a pizza in 3 slices the slices are bigger and if u take 2 out of the three the remaining piece is bigger than the 4/5 because those 5 pieces will be cut smaller
