Aleksandr [31]3 years ago
3 0

Answer:

A triangle equals to 180. Given that it is a right triangle, one angle should be 90.

So, 90+20 = 110

180-110= 70

Therefore, the other two angles are 90 and 70.

Factor the polynomial expression 4x2 +9.
Yanka [14]

Answer:

Step-by-step explanation:

Factor it by first setting it equal to 0:

4x^2+9=0 Now subtract 9 from both sides:

4x^2=-9 Divide both sides by 4:

x^2=-\frac{9}{4} Then take the square root of both sides:

x = ±\sqrt{-\frac{9}{4} } , which of course is not allowed. Therefore, we have to allow for the imaginary numbers in this solution. Knowing that,

x = ±\sqrt{-1*\frac{9}{4} } is an equivalent radicand, we can now replace -1 with its imaginary counterpart:

x = ±\sqrt{i^2*\frac{9}{4} }

Each one of the elements in the radicand are perfect squares, so we simplify as follows:

x = ±\frac{3}{2}i

And there you go!

Solve for x in the equation 3x^2 + 17x + 4 = -6
Sever21 [200]
Subtract -6 from both sides
3x^2 + 17x + 4 - (-6) = -6 - (-6)
3x^2 + 17x + 10 = 0

factor left side of equation
(3x+2)(x+5)=0

set factors to 0
x = -2/3 OR x = -5

I would go with -5
