X - 5 = x^2
i) 0 - 5 = -5^2 = 25
ii) 4 - 5 = -1^2 = 1
iii) -4 - 5 = -9^2 = 81
Answer:
If the x is a multiplying sign then the answer is 6, but
if the x is the letter x then it will be x=4
X = 2
<span>y = 3 </span>
<span>2 + 3 = 5 </span>
<span>2³ + 3² = 17 </span>
<span>------------------- </span>
<span>BUT: </span>
<span>x + y = 5 </span>
<span>x^y + y^ x = 17 </span>
<span>y = 5 - x</span>

15. any number and 0 will have a quotient of 0.
for example 7/0=0 . 8/0=0 . 9/0=0
if you try and check your work using multiplication 7*0=0 . 8*0=0 . 9*0=0
then you will realize the rule is right
