Answer:
Step-by-step explanation:
Let
be the greater number and
be the smaller number. We know that their difference is 15, so we have

Then, we have the following information: if we add twice the greater (2x) and 8 (2x+8), the result is 3 times the lesser (3y) minus four (3y-4). So, we have

So, we have the follwing system:

From the first equation, we can derive
, and substitute this expression in the second equation to get

Substitute this value for y in the first equation to get

9 x 3 = 27
27/9=3
12 x 3= 36
36/3=12
ANSWER: 36cm^2
Answer:
Hello,
p=4
q=7
Step-by-step explanation:
The vertex of the parabola is (-2,3)
Equation of the parabola is k(x+2)²+3=x²+px+q
Let's identify the coefficients:
kx²+4kx+4k+3=x²+px+q
so
k=1
4*1=p
4*1+3=q
