Simplify the expression 2√ 20 − 3√ 7 − 2√ 5 + 4√ 63 .

earnstyle [38]

Answer:

The simplified form is,

$\boxed{\boxed{6\sqrt{5}+9\sqrt{7}}}$

Step-by-step explanation:

The given expression is,

$=2\sqrt{20}-3\sqrt{7}+2\sqrt{5}+4\sqrt{63}$

$=2\sqrt{4\times 5}-3\sqrt{7}+2\sqrt{5}+4\sqrt{9\times 7}$

$=2(\sqrt{4}\times \sqrt{5})-3\sqrt{7}+2\sqrt{5}+4(\sqrt{9}\times \sqrt{7})$

$=2(2\times \sqrt{5})-3\sqrt{7}+2\sqrt{5}+4(3\times \sqrt{7})$

$=4\sqrt{5}-3\sqrt{7}+2\sqrt{5}+12\sqrt{7}$

$=4\sqrt{5}+2\sqrt{5}+12\sqrt{7}-3\sqrt{7}$

$=6\sqrt{5}+9\sqrt{7}$

Can someone help me thx

Answer: 118

Explanation:

Since ∠A=∠ADB: ∠ADB=61°. The sum of the interior angles of any triangle is 180°, thus:

61°+61°= 122
180-122=58°
∠DBA=58°

Since triangle BCD is an equilateral triangle, all the interior angles are the same:

180/3=60
∠DBC=60°
∠BCD=60°
∠CDB=60°

Since angles DBC and DBA make up angle ABC, just simply add the two angles together:

58+60=118°

Therefore, ∠ABC is 118°.

Answer:

$x = \frac{15}{4}$

Step-by-step explanation:

b) set up equations so they are equal to each other,

$2x - 2 = - 3x + 12$

$5x = 14$

$x = \frac{14}{5}$

this is when f(x)=g(x) so our approximation was close.

c)solving it graphically is nearly impossible because the solution can be any value around the intersection. only way to be sure is to solve it symbolically.
