4a2-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 :  4  is the square of  2  

Check :  a2  is the square of  a1  

Check :  b2  is the square of  b1  

Factorization is :       (2a + b)  •  (2a - b)  

Final result :

 (2a + b) • (2a - b)

Write the word sentence as an inequality. Then solve the inequality. The quotient of a number x and 4 is at most 5.
Charra [1.4K]

Answer:

Given the statement: The quotient of a number x and 4 is atmost 5.

Let x be a number.

"quotient of a number x and 4" represented as \frac{x}{4}

"at most" means '\leq'

Therefore, the inequality for the given statement is;

\frac{x}{4}\leq 5

Solve the above inequality:

\frac{x}{4}\leq 5

multiply both sides by 4 we get;

4 \times \frac{x}{4} \leq 4 \times 5

Simplify:

x\leq 20

Therefore, the solutions for the given inequality is:  (-\infty , 20]

Carmen spent a total of $19.50 at a concession stand on snacks for herself and her friends hamburgers cost $3.50 and hotdogs cos
Svetllana [295]
Hb=3.5, hd=2.25, hb+hd=7, 

From the third, we can say hb=7-hd and we are told that:

3.5hb+2.25hd=19.5  using hb found above in this equation gives you:

3.5(7-hd)+2.25hd=19.5

24.5-3.5hd+2.25hd=19.5

-1.25hd=-5

hd=4

Carmen bought 4 hotdogs.
