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:</h2>
(a) 6
(b) 9
<h2>
Step-by-step explanation:</h2>
The units of a whole number is the rightmost digit in the number. For example, if the number is <em>15678</em>, the units is <em>8</em> since that is the rightmost digit. Another example is <em>25795</em>. The units is <em>5.</em>
<em></em>
(a) To find the units of the square of -2346,
<em>i. First find the square of (-2346)</em>
(-2346)² = (-2346) x (-2346) = 5503716
<em>ii. Now find the rightmost digit.</em>
The rightmost digit of 5503716 is 6.
<em>Therefore, the units of the square of (-2346) is </em><em>6</em>

(b) To find the units of the square of -5677,
<em>i. First find the square of (-5677)</em>
(-5677)² = (-5677) x (-5677) = 32228329
<em>ii. Now find the rightmost digit.</em>
The rightmost digit of 32228329 is 9.
<em>Therefore, the units of the square of (-5677) is </em><em>9</em>
