Answer:
29
Step-by-step explanation:
x=4. 4-1=3. 7x3=21. 21+8=29. Viola
The process used in the picture is cross multiplying. Make an x through the numbers and multiply them by each other. That's why 21 was multiplied by 14 and 49 was multiplied by n. The value of n is unknown, so it simplifies to 49n, and 14*21=21.4. So basically to recap, make an x, multiply the terms that are diagonal from each other, write both of the answers next to each other, and put an = sign in between them. If you don't understand I can try to explain differently ☺
Make an equation where
Y =
(any number not zero) times X² + (any number at all) times X + (any number at all)
The graph of that equation is guaranteed to be a parabola.
Answer:
the answer is 9 and 8
Step-by-step explanation:
because 9 times 8 equal 72 which means 9 and 8 can be found as a square root of 72.
