Describe the nature of the roots for this equation.
kirza4 [7]

Answer:

Option D. two complex roots

Step-by-step explanation:

we know that

In a quadratic equation of the form ax^{2} +bx+c=0 the discriminant D is equal to

D=(b^{2}-4ac)

in this problem we have

3x^{2} -2x+1=0  

so

a=3\\b=-2\\c=1

substitute the values

D=(-2^{2}-4(3)(1))

D=(4-12)

D=-8

The discriminant is negative

therefore

The quadratic equation has two complex roots

Factor 200t+83 - 80t2.<br> A. 8t(t - 5)(t + 5)<br> B. 8t(t - 5)2<br> C. -8t(t - 5)(t + 5)
Mashutka [201]

Step-by-step explanation:

8t³-80t²+200t

= 8(t³-10t+25)

= 8t(t²-10t+25)

= 8t(t-5)(t-5)

= 8t(t-5)²

the answer is B.

Please help me answer the question.ghvjhbikb
rjkz [21]

Answer:

240units^2

Step-by-step explanation:

The formula for area on a triangle is 1/2 x b x h, so you do 4 x 10 x 1/2, giving you 20, there are two of these triangles so you double it to 40.

Then for the rectangle below you do l x w, or 10 x 20 giving 200.

You then add it all together, 200+20+20=240 units squared.

Hope this helps!
