Answer: A quadratic equation is one of the form ax2 + bx + c = 0, where a, b, and c are numbers, and a is not equal to 0. So I think x = 4 but not 100%
Sorry if I'm wrong but I hope this helps
Answer:
Step-by-step explanation:
The top left angle of the triangle is 62°, we know because we are shown that the exterior angle outside that part of the triangle is 28°, so 62° would make that a corner.
We can use Tan of this angle to find the missing side (in this case, the side opposite of the angle measuing 62°)
Tan A = (opposite side)/(adjacent side)
Tan 62° = y/350
solve for y
350(Tan 62°) = y
658.3 = y (rounded to the nearest tenth)
So you have your polynomial. To factor this out, you need to find the factors of -45 that will add up to 3. These two factors would be -5 and 8. So, you have factored your polynomial! (x-5)(x+8). If you are still unsure, simply use the FOIL method to check and see if you get the same polynomial back. Hope this helps!
Answer: ten-thousandth's place
I probably spelled it wrong sorry lol. Spelling isn't my thing :)
Hope I helped!
