Expand and simplify

likoan [24]

Answer:

5 $\sqrt{2}$ + $\sqrt{10}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Given

$\sqrt{5}$ ( $\sqrt{10}$ + $\sqrt{2}$ ) ← distribute

= $\sqrt{50}$ + $\sqrt{10}$

= $\sqrt{25(2)}$ + $\sqrt{10}$

= $\sqrt{25}$ × $\sqrt{2}$ + $\sqrt{10}$

= 5 $\sqrt{2}$ + $\sqrt{10}$

Roberto tool a test that contained 25 questions. He received an 88% on the test. how many questions did he answer correctly?

iren [92.7K]

He got 22/25 questions right because

if you put X as the number of questions he got right out of 25 and equal it to 88 out of 100 you can cross multiply to get X

x/25=88/100
100x=25×88

25×88=2200
100x=2200

divide 100 on both sides
therefore
2200/100= 22

hope this helps
