Answer:
around 76.16
Step-by-step explanation:
30 squared + 70 squared = 5800
square root of 5800 = 76.16
a squared + b squared = c squared
What are the units? Tell me the units so I can solve this please.
Answer:
⇒ The given quadratic equation is x2−kx+9=0, comparing it with ax2+bx+c=0
∴ We get, a=1b=−k,c=9
⇒ It is given that roots are real and distinct.
∴ b2−4ac>0
⇒ (−k)2−4(1)(9)>0
⇒ k2−36>0
⇒ k2>36
⇒ k>6 or k<−6
∴ We can see values of k given in question are correct.
Answer:
Add 5 for the first one
The 2nd one is 25 and k or 25 thousand.
Step-by-step explanation:
add 5 for the first one because 5 + 5 = 10
9 + 5 = 14 . and 13 + 5 = 18.
------------------------------------------------------------------
For the 2nd one: 25k means 25 thousand or the Product of 25 and k.
<span>$60.00 - $42.00 = </span><span>$18
</span><span>$18 / $60 = 0.30 = 30%
Answer
Decrease 30%</span>
