Brynn and Denise launch their rockets at the same time. The height of Brynn’s rocket, in meters, is given by the function f(x)=−

4.9 x 2 +75x , where x is the number of seconds after the launch. The height of Denise’s rocket, in meters, is given by the function g(x)=−4.9 x 2 +50x+38 , where x is the number of seconds after the launch. There is a moment when the rockets are at the same height. What is this height? Enter your answer, rounded to the nearest tenth of a meter, in the box

A2-b2 ÷5a-5b factorise​
katrin2010 [14]

Answer:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "b2"   was replaced by   "b^2".  1 more similar replacement(s).

STEP

1

:

           5a + 5b

Simplify   ———————

           a2 - b2

STEP

2

:

Pulling out like terms

2.1     Pull out like factors :

  5a + 5b  =   5 • (a + b)  

Trying to factor as a Difference of Squares:

2.2      Factoring:  a2 - b2  

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check :  a2  is the square of  a1  

Check :  b2  is the square of  b1  

Factorization is :       (a + b)  •  (a - b)  

Canceling Out :

2.3    Cancel out  (a + b)  which appears on both sides of the fraction line.

Final result :

   5 / a -b

In a​ poll, 22​% of 714 surveyed adults said that . What is the actual number of adults who said that
Eva8 [605]

Answer:

<h2> 157 surveyed adult </h2>

Step-by-step explanation:

IF 22% of 714 surveyed adult made a statement, the actual number of those that made the statement can be gotten by simply evaluating 22% of 714 as shown below;

= 22% of 714

= 22/100 * 714

= (22*714)/100

= 15708/100

= 157.08

≈ 157 surveyed adult

<em>This means that about 157 surveyed adults made the statement. </em>
