90 = -9×-10 = 10×9

The number could be either -9 or +10.

_____
You can solve this based only on your knowledge of the factors of 90. If you like, you can write an equation ...
  x(x-1) = 90
  x² - x - 90 = 0
Factoring this has you seeking factors of 90 that differ by 1, the same as the original problem does. Of course, you can solve this by other means, including the quadratic formula or completing the square or graphing.

Roland said it is possible to make a triangle from the following lengths: 31 inches, 70
dlinn [17]

Answer:

the teacher should be sad. the correct answer is 68 inches is NOT greater than 70 inches, therefore a triangle can't be created

Step-by-step explanation:

in a triangle, 2 sides added together have to be greater than the third side or else the triangle can't be created. therefore, since 31+37=68 inches, and 68<70, the triangle can't be created.

Determine if x=-16 is a zero &amp; find the quotiant and the remainder​
DerKrebs [107]

Answer:

○ A. No, x = -16 is not a zero of the polynomial.

The quotient is x² - 2x + 83, and the remainder is -1274.

Step-by-step explanation:

This is not a zero. When set to equal zero, you get these roots: -2, -3, -9. Now, about the the Remainder Theorem, I have not been taught this, but just by looking at it, I come across this as the remainder.

I am joyous to assist you anytime.

* I cross my fingers for it to be correct!
