Answer:
a) GCF = 8
Step-by-step explanation:
b)
Well for 3. you use the Pythagorean theorem to say that 28^2 - 18^2= x^2 so 21.4 and for 4. the Pythagorean theorem says a^2 + b^2 = c^2 with c being the hypotenuse of any right triangle so the sums of the two smaller squares make the sum of the larger square making the answer b
The answer is 104.
1/4 of 104 is 26, 104 - 26 = 78
78 - 7 = $71
