Please help! Not even sure how to start with this one or how to calculate
vivado [14]

Remember when you learning about the "Least Common
Multiple" and you wondered when in the world you would
ever need to use it ?
Well, here you are !   Hello !

The next time they will cross the starting line together is the
LCM (Least Common Multiple) of 30 and 40 .

Do you remember how to find it ?
Here's one easy way: 

Count by 30s until you come to a number that's divisible by 40 .

Laura's first lap. . . . . . . . 30 seconds . . . not divisible by 40
Laura's two laps . . . . . . . 60 seconds . . . not divisible by 40
Laura's three laps. . . . . . 90 seconds . . . not divisible by 40
Laura's four laps. . . . . . 120 seconds . . . divisible by 40

After 120 seconds, Laura has completed four laps,
Shelby has completed only three laps.

Please help me with this quadratic equation question! I always give out 5 stars, thanks and brainliest to people that help me wi
ss7ja [257]

Answer:

p=25,\\q=12

Step-by-step explanation:

In (ax+b)(cx+d)=acx^2+bcx+dax+bd, notice the third term of the quadratic in standard form is formed entirely by b\cdot d.

Therefore, in 12x^2 - 13x - 7175 = (x-p) (qx + 287):

-p\cdot287=-7175,\\-p=\frac{-7175}{287},\\p=\fbox{$25$}.

Now that we found p, we must find q. The first term of the quadratic in standard form is formed entirely by ax\cdot cx. Therefore:

1\cdot q=12, \\q=\fbox{$12$}.
