Answer:
x^2-2x-13
Step-by-step explanation:
f(x) = 2x-5
g(x) = x^2 -4x-8
f(x) +g(x) = 2x-5 + x^2 -4x-8
Combine like terms
= x^2+2x-4x-5-8
=x^2-2x-13
Answer:
1) Standardization
2). 1:1.25
3) 4cm
Step-by-step explanation:
The manipulation of scale variables to ensure comparability with other scales and enable comparisons to be made.
1:x = 9.6:12
x= 1: 1.25
9.6/12 = AC/5
AC= (5*9.6)/12
AC= 48/12
AC= 4cm
-6x+12 because you are multiplying -3 and 2x and -3 and -4
12x+10-5x
12x-5x+10 ( combine like terms)
12x-5x= 7x
Answer: 7x+10
We know that 1 foot is 12 inches then, we change all quantities to inches to ease the calculations:
5 ft 9 in = 5(12) + 9 = 60 + 9 = 69 inches
10 ft 11 in = 10(12) + 11 = 120 + 11 = 131 inches
so we add:
<span>5 ft 9 in + 10 ft 11 in
= 69 inches + 131 inches
= 200 inches
if we want the result in foot we divide:
= 200/12
= 100/6 = 50/3
= 16 ft 8 in</span>
