One of two complementary angles measures 30 degrees more than three times the other. Find each angle.

Leviafan [203]

The two complementary angles are:

95° and 15°

Step-by-step explanation:

Let x be one angle

then the other angle will be 90-x

As the sum of complementary angles is 90

So,

then according to statement

$x = 3(90-x)+30\\x = 270-3x +30\\x = 300-3x\\x+3x = 300\\4x = 300\\x = \frac{300}[4}\\x = 75\\and\\90 -x = 90 - 75 = 15$

The two complementary angles are:

95° and 15°

(4x²-5x+10)+ (6x³+7x²-9x+2) MAKE THIS IN ALGEBRA TILES NONSENSE ANSWER REPORT

ruslelena [56]

Answer:

6x^3+11x^2-14x+12

Step-by-step explanation:

We just simply add like terms (terms with same power of x):

$6x^3+(4x^2+7x^2)+(-5x+-9x)+(2+10)$

Like terms are in brackets now

So you just simplify now to give you:

$6x^3+11x^2-14x+12$
