-11/-11 = 1
Anwser
15/ 25
Step by step explanation
With exponents you don’t multiply them by the number you multiply them the amount of times the number says so if a is one you multiply 1×1×1 which is one then you move on to B both times has it exponent of 2 so 3×3 is nine and 9×1 is 10. And since there is no exponent Over C, you can just add 10+5 which is 15
Now on the bottom half you see that C doesn’t have an exponent so we can figure out a is 1 then, do you see that b has the same exponent of two we are just going to bring that nine down to the lower half now as you can see, C has an exponent 5×5×5 is 15 and 15+10 = 25
Ps. Hope this helps!

Answer:
The width is 9.5 ft
Step-by-step explanation:
Perimeter for a rectangle is given by
P = 2 (l+w)
43.8 = 2 (12.4+w)
Divide each side by 2
21.9 = 12.4+w
Subtract 12.4 from each side
21.9-12.4 = w
9.5 = w
The width is 9.5 ft
(2,-1), (-4,17).
Step-by-step explanation:
Equate the equation A and equation B
Convert the quadratic equation in factored form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
Square root both sides
Find the values of y
Substitute the value of x in the equation B
