Answer:
4x^2 + 4x + 3.
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 5x^2 - 3 - (x^2 - 4x - 6)
= 5x^2 - 3 - x^2 + 4x + 6
= 4x^2 + 4x + 3.
Which one is underline digit. 6 is in ones place cause its on the left side of the decimal. 5 is tenths and 4 is hundredths place :) hope this helps

Answer:
5cm wide, 10cm long.
Step-by-step explanation:
I came to this answer by looking for common factors between 50 and 5, and I found 10.
5cm + 5cm = 10cm, so it works.
To confirm this, I multiplied 5 and 10 and got 50cm (squared) which works.
2 consecutive positive integers....x and x + 1
" the product " means multiply and " the sum " means add
x(x + 1) = x + (x + 1) + 1
x^2 + x = 2x + 2
x^2 - 2x + x - 2 = 0
x^2 - x - 2 = 0
(x + 1)(x - 2) = 0
x + 1 = 0
x = -1......not this one because it is negative
x - 2 = 0
x = 2
x + 1 = 2 + 1 = 3
so ur numbers are : 2 and 3 <==
