Simplify 5 square root of 7 end root plus 12 square root of 6 end root minus 10 square root of 7 end root minus 5 square root of

Alinara [238K]

Answer:

So, the simplified version is

$-5\sqrt{7}+7\sqrt{6}$

In words it can be written as minus 5 square root of 7 end root plus 7 square root of 6 end root

Step-by-step explanation:

$5\sqrt{7}+12\sqrt{6}-10\sqrt{7}-5\sqrt{6}$

We need to simplify the above expression.

Combining the like terms of the above expression.

Like terms are those that have same variables.

$=(5\sqrt{7}-10\sqrt{7})+(12\sqrt{6}-5\sqrt{6})$

$=((5-10)(\sqrt{7})+((12-5)(\sqrt{6}))$

$=((-5)(\sqrt{7})+((7)(\sqrt{6}))$

So, the simplified version is

$-5\sqrt{7}+7\sqrt{6}$

In words it can be written as minus 5 square root of 7 end root plus 7 square root of 6

If f(x) = 5x²+2x-10, find f(6) - f (3)

vlada-n [284]

Answer:

681

Step-by-step explanation:

5x6=30

30x30=900

2x6=12-10=2

900+2=902

5x3=15

15x15=225

2x3=6

6-10=-4

225-4=221

902-221=681

(a) If cos² (34°) - sin² (34°) = cos(A°),then<br> A =<br> degree’s

krok68 [10]

$~~~~~~~\cos^2 \left(34^{\circ}\right) - \sin^2 \left( 34^{\circ} \right)=\cos A\\\\\implies \cos \left( 2 \cdot 34^{\circ} \right) = \cos A~~~~~~~~~~~~~;[\cos 2x = \cos^2 x -\sin^2 x]\\\\\implies \cos \left(68^{\circ}\right) = \cos A\\\\\implies A = 68^{\circ}$
