b) Identity Property of Multiplication
c) Identity Property of Addition
d) Associative Property of Addition.
Step-by-step explanation:
7/8 is greater because 8/9 you’ll get less out of it
No, they are both incorrect by my understanding of your question use the Pythagorean theorem a^2 + b^2 =c^, therefore, 7^2 +x^2 = 13^2 or 49+x=169 then solve normally 169-49=120 √120 =5
The answer is 5
W-5=5
W= 5+5 (bringing -5 to the other side, it becomes +5)
At last, W=10.
