Area of rectangle : A = LW
19. A = 3p^4 * p^2 = 3p^6 (when multiplying exponents with the same base, u add the exponents)
20. A = 7z^5 * 6z^3 = 42z^8 (because 7 x 6 = 42, and z^5 * z^3 = z^8)
Answer:
The student took the numbers for the factors 5, -4 for the zeros instead of solving the equation
The zeros are -5, 4
Step-by-step explanation:
x^2 +x - 20=0
What 2 number multiply to -20 and add to 1
5*-4 = -20
5+-4 = 1
(x+5)(x-4) =0
Using the zero product property
x+5 = 0 x-4 =0
x=-5 x=4
The answer is B and put the question next time
