Answer:
This not True
Step-by-step explanation:
x-3=± 4 (mistakes)
x=3±4
x=3+4 and x=3-4
x=7 x=-1
Step-by-step explanation:
its say $3.50 each so for a week you multiply $3.50 by 3 because the are 3 days which will be equal to $10.5
the you divide $84 by $10.5
and the answer is =8weeks
C; a percent is out of 100. All you have to do is change the denominator into 100. Since 5x20=100, you have to multiply 3/5 top and bottom by 20. Your product should be 60.
Using the FOIL (First, Outside, Inner, Last) method, you multiply the two parenthesis together. First, you multiply x • x which = x^2, then outside, x • -3 = -3x. Next you multiply the inner number and variable, 2 • x = 2x, and finally the last values, 2 • -3 = -6. Then add all the values together (x^2 - 3x + 2x - 6) which equals the final answer x^2 - x - 6 :) Im not great at explaining but I hope this helps
