Answer:
=3
=2
Step-by-step explanation:
12−5+6=0
using the Quadratic Formula where
a = 1, b = -5, and c = 6
=−±2−4‾‾‾‾‾‾‾‾√2
=−(−5)±(−5)2−4(1)(6)‾‾‾‾‾‾‾‾‾‾‾‾‾‾√2(1)
=5±25−24‾‾‾‾‾‾‾√2
=5±1‾√2
The discriminant 2−4>0
so, there are two real roots.
Simplify the Radical:
=5±12
=62=42
which becomes
=3
=2
hope this helps :)
Answer: 7
step-by-step:
okay so first you do 7*5 which is 35 and 20+8 which is 28
then you get 35=28+x (the x is the ‘missing number’)
to find x you subtract 28 from both sides to keep the equation balanced
35-28=28-28+x
so 35-28 is 7 and 28-28 is 0 so then you have 7=x and your answer is 7
you’re doing algebra but instead of using variables your teacher is saying find the ‘missing number’ haha
Divide 462 by 49 then you got your answer for Jack
Google how many feet are in a mile and take that amount of feet then divide it by 407 that’s your answer for Will
Divide 681 by 60 standing for 60 seconds in one minute then that’s your answer for Liz
Since they already gave you the answer to Jack see which amount is the highest
Hope this helped :)
