Answer:
True
Step-by-step explanation:
Answer:
the third one
Step-by-step explanation:
Answer: b
Step-by-step explanation:
10 x 10= 100
15 x 10= 150
100+150= 250
You can find the number of x intercepts by setting f(x) equal to zero giving you 0=x^4-5x^2. You can factor out an x^2 and divide on both sides (when you divide 0 by anything it is still zero so the x^2 disappears), and you are left with 0=x^2-5, which you can solve easily giving you x=+/- sqrt(5). However, the original equation also has an x intercept at (0,0) which you can see by plugging 0 in for x. So the grand total of x intercepts is 3!
It’s an isosceles triangle, so those two sides are equal:
3x-15=x+33
2x=48
x=24, so BC should be 24.
