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{$12$}.

What are the values of x and y?
scZoUnD [109]

Answer:

x is equal to 24 and y is equal to 66.

Step-by-step explanation:

In order to find the value of y, we first have to note that the unlabeled angle in the larger triangle, y and the 78 degree angle create a straight line. The unlabeled angle is equal to 36 since it and the other two angles equal 180. So we take that 36, 78 and y and can set that equal to 180.

36 + 78 + y = 180

114 + y = 180

y = 66

Now that we have that value, we can use y and the 90 degree angle to find x.

x + y + 90 = 180

x + 66 + 90 = 180

x + 156 = 180

x = 24
