Answer:
x^3+3x^2-7x+15
Step-by-step explanation:
first you've got to distribute x through (x^2-2x+3)
x^3-2x^2+3x, then distribute the 5 through (x^2-2x+3)
5x^2-10x+15 now you add that to x^3-2x^2+3x
x^3+3x^2-7x+15
Let the length be x
Area = x²
Perimeter = 4x
<span>Area of a square is 3 times its perimeter
</span>⇒ x² = 3(4x)
x² = 3(4x)
x² = 12x
x² - 12x = 0
x(x - 12) = 0
x = 0 or x = 12
Since x cannot be zero, x = 12
Answer: The length is 12 units.
45 divided by 9 is 5 so 5 times 2 is 10. So theirs 10 girls at the park
Answer:
Student has made an error
Step-by-step explanation:
If two figures are said to be congruent, this implies that area of both is same and both as exactly same or copy or each other.
But from the graph, it can be stated that height of figure JKLM is 4 units whereas that of other is 6 unit.
