7x² + 3x = 0
x(7x + 3) = 0 ⇔ x = 0 or 7x + 3 = 0 |subtract 3 from both sides
x = 0 or 7x = -3 |divide both sides by 7
x = 0 or x = - 3/7
Answer: B. {0; -3/7}
Answer:
13 inches
Step-by-step explanation:
Perimeter is all the sides added so your equation would be 8+8+x+x=42 then you combine like terms. 16+2x=42. Next you would isolate the variable 2x=26 and the divide the 2 on both sides and you get x=13. Meaning your width is 13 inches long
Answer:
(a) greater
Step-by-step explanation:
When comparing numbers, it is helpful to have them in the same form. You could express them both as fractions with the same denominator, as percentages, as decimals, or any other form you like.
walk to school: 18%
close to school: 11/50 = 22/100 = 22% . . . (greater than 18%)
The portion of students who live within 1/2 mile of school is greater than the portion who walk to school.
_____
<em>Additional comment</em>
The % symbol essentially means /100.
Then 18% = 18/100 = 9/50. The fraction 11/50 is greater than this.
