The quadratic equation is in factored form, which is f(x) = (x - a)(x - b), where a and b are the x-values for the x-intercepts.
The x-values for the x-intercepts are 4 and -2. We know that the y-value at any x-intercept must be 0 (otherwise it isn't an x-intercept).
Thus, either the points (4,0) or (-2,0) must be your answer (the question is only asking for one x-intercept).
4 units because the y-intercept is how you figure out the difference. You take the y-intercept, find the absolute value of it, and you found the distance of the line! This is of course considering the lines are parallel, meaning the slope is the same.
Answer:
Am = 1500 cm²
Step-by-step explanation:
If you mean leg around the right angle a = 3 cm and b = 5 cm then :
Formula for calculating area of the right triangle is:
A = a · b / 2 since we have 200 triangles, area of the mosaic is:
Am = 200 · A = 200 · a b / 2 = 200 · 3 · 5 / 2 = 1500 cm²
Am = 1500 cm²
God with you!!!
