andreev551 [17]

Answer:

The distance, in feet, between the strip = 12 feet.

Step-by-step explanation:

From the figure attached in relation with the question, we can deduce that crosswalk is a parallelogram where

CD/AB = CE/AE

CD = 40

CE = 50

AE = 15

Let AB = x

50x = 15 × 40

X = 12

 The distance, in feet, between the strip is therefore 12 feet

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{$12$}.
