<em>75</em>
Step-by-step explanation:
Subtracting a number means adding the opposite.
The opposite of a number is the number you obtain by just changing the sign.
The opposite of 5 is -5. The opposite of 100 is -100. The opposite of -4.5 is 4.5. The opposite of 0 is 0. Zero is the only number that is equal to its opposite.
You need to subtract -45, so add the opposite of -45 which is 45.
30 - (-45) = 30 + 45 = 75

<h2>The answer is 32</h2>
Step-by-step explanation:
3( 2c + d) - 4( c - d) + d²
when
c = 1
d = 3
Substitute the values of c and d into the expression and solve
That's
3[ 2(1) + 3 ] - 4( 1 - 3) + 3²
= 3( 2 + 3) - 4( - 2) + 9
= 3(5) + 8 + 9
= 15 + 17
We have the final answer as
<h3>32</h3>
