Answer:
4x^2-16x-20
Step-by-step explanation:
(x-5)(x+1)=x^2-5x+x-5=x^2-4x-5
leading coefficient=4
which means that 4(x^2-4x-5)=4x^2-16x-20 is the answer.

Answer:
(11/7 , 18/7)
Explanation:
The second given equation is:
y = x + 1 ............> I
The first given equation is:
y = -2.5 x + 6.5 ..............> II
Substitute with I in II and solve for x as follows:
y = -2.5 x + 6.5
x + 1 = -2.5 x + 6.5
x + 2.5 x = 6.5 - 1
3.5 x = 5.5
x = 11/7
Now, substitute with x in equation I to get y as follows:
y = x + 1
y = 11/7 + 1
y = 18/7
Hope this helps :)
Use Pythagoras theorem that is ( h^2= p^2+b^2 ) but it depends what sort of a triangle is it
47-25= 22
22 divided by 47 =0.468 aka 47% increase
