In the following exercises, multiply the binomials. Use any method.<br> 248. (m + 11)(m − 4)

romanna [79]

Answer:

Hence the expression $(m+11)(m-4)=m^2+7m-44$

Step-by-step explanation:

Explanation

The given expression is (m+11)(m-4).
We have to multiply the given expression.
Multiply the (m+11) by -4, multiply the (m+11) by m then add like terms.

$$$\frac{\begin{matrix}{} & {} & m & + & 11 \\ \times & {} & m & - & 4 \\ \end{matrix}}$

_____________

${\frac{\begin{matrix}{} & - & 4m & - & 44 \\ {{m}^2} & + & 11m & {} & {} \\ \end{matrix}}{\begin{matrix}{{m}^2} & + & 7m & - & 44 \\ \end{matrix}}}$$$

36 is 75% of what number

g100num [7]

Learn this and it can answer all ur percent problems
percent formula : is/of = %/100

36 is 75% of what number...
is = 36
% = 75
of = x.....because that is what u are looking for.
now sub into the percent formula

is/of = %/100
36/x = 75/100
cross multiply because this is a proportion
75x = 36(100)
75x = 3600
x = 3600/75
x = 48

so 36 is 75% of 48

Solve the inequality -1/2x -3 ≤ -2.5

IgorLugansk [536]

Answer:

x ≥-1

Step-by-step explanation:

-1/2x -3 ≤ -2.5

Add 3 to each side

-1/2x -3+3 ≤ -2.5+3

-1/2x ≤ .5

Multiply each side by -2, remembering to flip the inequality

-2 * -1/2x ≥ 1/2 * -2

x ≥-1

The double number line shows that 444 bottles of water cost 101010 dollars at a music festival. Based on the ratio shown in the

MrRissso [65]

Answer:

Please see the attachment for double number line.

Explanation:

We are given cost of 4 water bottles is $10

We can write ,

Cost of 4 bottles = $10

Cost of 1 bottle = $2.5

Cost of 2 bottles =$5

Cost of 3 bottles = $3\times 2.5$ = $7.5

Cost of n bottles = $2.5n

Now we draw the double number line.

Bottom line(Line 1) will take as number of bottles:

1 2 3 4 5 6

Above line (Line 2) will show the cost of corresponding number of bottles:

2.5 5 7.5 10 12.5 15
