There are a total of 32 problems.
Assumed all 32 problems are 3 points questions ⇒ 32 x 3 = 96 points.
The test is worth 111 points, so there is an extra of 111-96 points = 15 points.
The difference in points in the 2 type of questions is 4 - 3 = 1 points.
Number of 4 points questions = 15 ÷ 1 = 15.
Number of 3 points questions = 32 - 15 = 17.
Answer: There are 17 3-points questions and 15 4-points questions.
Answer:
The given equation has two solutions i.e 
, 
Step-by-step explanation:
The given expression as :
3 x² + 2 x - 4
For the quadratic equation in the form of a x² + b x + c , the value of x
x = 
Or, x = 
Or, x = 
or, x = 
∴ x = 
Or, x = ,
Hence The given equation has two solutions i.e , Answer
A = 34 x 2 = 68
b = 56/2 = 28
hope it helps

Step-by-step explanation:
Answer:
Step-by-step explanation:
Since pqrs is a quadrilateral
Total interior angle = 360 (keep in mind)
>PSR = 360-(65+130+95)
>PSR= 360-290= 70
* PST is a straight line :- >PSR + Y = 180 (sum of angle on a straight line)
:. Y= 180-70= 110.
