Answer:
Step-by-step explanation:
You need to get w on one side by itself.
Start out by subtracting 2l from both sides.
p−2l=2w.
Now since w is being multiplied by 2 we need to divided both sides (all terms) by 2.
w=p2−I
Solve for x in each set of parentheses by setting them to 0:
X -8 = 0
X = 8
X+9 = 0
X =-9
You have two x intercepts (8,0) and (-9,0)
You didn’t list any choices to pick from but it would be either if the ones above.
Answer:
x=-16
Step-by-step explanation:
Subtract 4 from both sides
x+4-4=-12-4
x=-16
Answer:
70/5985
Step-by-step explanation:
We know that a quadrilateral needs to have four vertices (or points on the circle). There are always two ways to link the cross — horizontally or vertically. Using my limited knowledge of combinations, we know that choosing four points out of seven equals 35. Multiplying the two ways to connect those lines (again, horizontally and vertically) makes 35*2 = 70 "bow-tie quadrilaterals" that can be formed on the circle using four points. There are 5985 ways four chords can be chosen out of twenty-five chords because C(25,4) equals 5985, so the probability is 70/5985... and then we just need to simplify that fraction.
Answer:

Step-by-step explanation:
The formula is given as:

We need to solve this formula for v, that means that v to one side and let it be solved in terms of the other variables (E and m). First, we isolate v:

To isolate v, and eliminate the "square", we need to take square roots of both sides, that will give us v in terms of the other variables:

Putting v to left side (convention), we finally have:
