(repost) Can anyone answer these? questions:
1. Alexa knocked down 70 bowling pins in 10 frames. In each frame, Alexa knocked down the same number of pins. How many Pins did Alexa knock down in each frame?

2. Equation: 28 ÷ 4 = 7. Write a related multiplication sentence.

3. Bonnie had 6 bags of 6 gel pens. she wanted to give the same number of gel pens to 9 friends. How many gel pens did each friend get?

4. Show two ways to solve this problem: 4 × 3 × 2

5. Round each number to the nearest 100, Then Subtract. 187 - 69 is about?
(gosh im tired it took me forever to write this XD)

1.) 7 pins

2.)56 ÷ 8 = 7

3.)Each friend gets 4 pens

4.)(4x3)x2 and 4x(3x2)

5.) 100

Step-by-step explanation:

1.) 70 ÷10= 7

2.)28x 2 = 56

4 x 2= 8

3.)6 x 6 = 36

36 ÷ 9= 4

4.)(4 x 3 )x 2 or 4 x (3 x 2)

5.)187-69 =118

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
