9x² - 42x + 49 is a perfect square in that (3x-7)² is the factored version.
if the square has an area of 64square meters the value of x would be 5.
(3x - 7)² = 64 (get the square root of each side)
√(3x - 7)² = √64
3x - 7 = 8 (add 7 to both sides)
3x = 15 (divide both sides by 3)
x = 5
Answer: 3432.56
Step-by-step explanation: Everything is on the attached file, enjoy!!! If you have any further questions, just ask me, I'd be glad to help!
Alert: IDK if it is attached, so sorry if it isn't i'll try to explain it.
2490.05 is the initial value how much leo started with.
2.5% + 100% = 1.025
weekly =13weeks
multiply 1.025 by the sqrt of 13 since that's the amount of weeks.
that gets you 3432.56.
The answer is 7/2a because the denominators are already the same, therefore, you just add the numerators.
Answer:
13/200
Step-by-step explanation:
<em>so we grab the fraction:</em>
6 1/2%
<em>make it a decimal instead of a fraction</em>
6.5%
<em>divide it by 100 to get</em>
6.5/100
<em>and multiply it by 2 because decimals have no place inside fractions lol</em>
13/200
Answer:
105:175
Step-by-step explanation:
3+5 = 8
3/8 of 280 is 105.
5/8 of 280 is 175.
the ratio is 105:175
next we have to simplify it:
divide both sides by 5:
21:35 divide both sides by 7=
3:5
