When you multiply radical expressions you multiply the numbers under the radical symbols.<span><span>3–√</span>×<span>7–√</span>=<span>21<span>−−</span>√</span></span>
When you add radical expression you CANNOT add the numbers under the radical symbols.

<h2>Answer:</h2>
<u>In ΔQRS and ΔQLK</u>,
QR/QL = QS/QK
28/4 = 28/4
7/1 = 7/1 --[1]
<u>AngleLQK and AngleRQS are equal</u> (VOA)
<u>Two sides are in same proportion and the included angle is common (SAS) . Hence both the triangles are similar</u>.
[A] ΔQRS ~ ΔQLK by SAS similarity.
Answer:
Step-by-step explanation:
If a given variable varies inversely with another variable, an increase in the value of the given variable would cause a corresponding decrease in the value of the other variable. Also, a decrease in the value of the given variable would cause a corresponding increase in the value of the other variable.
If y varies inversely with x, we would introduce a cost of variation, k so that the expression becomes
y = k/x
When y = 0.25, x = 8
Substituting into the expression above, it becomes
0.25 = k/8
k = 0.25 × 8
k = 2
The inverse variation function is
y = 2/x
Ok I have the answers! Anything, whether positive or negative, with the value above .5 has a high correlation. Therefor the answers would be
B-low correlation
C-no correlation
D-low correlation
G- no correlation
I know that's too late for you but hope it helps with any other students struggling!
