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
vova2212 [387]
5 \sqrt{7}  + 12 \sqrt{6} -10 \sqrt{7} - 5 \sqrt{6}

Think of square roots of the same numbers as being like terms.

Think of

5x + 12y - 10x - 5y =

= 5x - 10x + 12y - 5y

= -5x + 7y

Think of sqrt(7) as x, and sqrt(6) as y.

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

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

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

= 7 \sqrt{6} - 5 \sqrt{7}

Angle Terminology with Equations
Sergeeva-Olga [200]

Answer:

∠ B = 54°

Step-by-step explanation:

Supplementary angles sum to 180°.

Sum A and B  and equate to 180, that is

7x + 14 + 5x - 26 = 180, that is

12x - 12 = 180 ( add 12 to both sides )

12x = 192 ( divide both sides by 12 )

x = 16

Thus

∠ B = 5x - 26 = 5(16) - 26 = 80 - 26 = 54°
