Answer:

Answer:

Step-by-step explanation:

(a) 4x2 -- 3x - 2 = 0

x1,2 = -b ± √b²- 4ac

         ---------------------

                  2a

    x1,2  = 3 ±√41

             --------------

                   8

(b) (2x - 3)2 = 6​

      4x² -12x + 9 -6 = 0

        4x² - 12 x + 3 = 0

Step-by-step explanation:

(a) 4x2 -- 3x - 2 = 0

x1,2 = -b ± √b²- 4ac

         ---------------------

                  2a

    x1,2  = 3 ±√41

             --------------

                   8

(b) (2x - 3)2 = 6​

      4x² -12x + 9 -6 = 0

        4x² - 12 x + 3 = 0

A triangle has angles that measure 46° and 61°. What is the measure of the third angle? A. 15° B. 73° C. 107° D. 134°
Nastasia [14]
The interior angles of a triangle need to be equal to 180°, so to solve this you need to figure out how many degrees you need to get 180°.

46 + 61 = 107

180 - 107 = 73

The measure of the third angle is B. 73°.

Whitepunk [10]
Total no. of hours you spent biking = 2 hours
the speed at which you rode your bike ≤ 17.6 mph
Now,
We have,
speed =  \frac{distance}{time}

17.6 =  \frac{distance}{2}

17.6 *2=  distance

35.2=distance

So, you for given conditions, you can't travel more then 35.3 miles

So, the inequality for the given circumstances is:
x ≤ 35.2
