Answer:
< means less than
example: 7 < 10
Step-by-step explanation:
Solve for x over the real numbers using factor method:
10 x^2 + 19 x - 15 = 0
The left hand side factors into a product with two terms:
(2 x + 5) (5 x - 3) = 0
Split into two equations:
2 x + 5 = 0 or 5 x - 3 = 0
Subtract 5 from both sides:
2 x = -5 or 5 x - 3 = 0
Divide both sides by 2:
x = -5/2 or 5 x - 3 = 0
Add 3 to both sides:
x = -5/2 or 5 x = 3
Divide both sides by 5:
Answer: x = -5/2 or x = 3/5
If the first rectangle has length, l, and width w then its perimeter is given by the following relation
2l+2w=72 divide by 2 on both sides so that the relation now becomes l+w=36
If l and w are scaled by a factor of 3.5, the new measurements of your resulting rectangle will 3.5l+3.5w-->3.5(l+w)
