Answer:

You will need 44 sq ft of carpeting

Step-by-step explanation:

First we can find the area of the larger rectangle and subtract the area of the smaller rectangle

Large rectangle:

equation for area: bh

= 12 * 4

=48 sq ft

Small rectangle:

equation: bh

= 2 * 2

=4 sq ft

48 - 4 = 44 sq ft

Answer:

44 square feet

Step-by-step explanation:

big one - small one

big one=12 x 4=48 square feet

small one=2 x 2=4 square feet

Find the distance between each pair of points. Round your answer to the nearest tenth, if necessary. Hint: Use the Pythagorean T

Paul [167]

The distance between two points on the plane is given by the formula below

$\begin{gathered} A=(x_1,y_1),B=(x_2,y_2) \\ \Rightarrow d(A,B)=\sqrt[]{(x_1-x_2)^2+(y_1-y_2)^2} \end{gathered}$

Therefore, in our case,

$A=(-1,-3),B=(5,2)$

Thus,

$\begin{gathered} \Rightarrow d(A,B)=\sqrt[]{(-1-5)^2+(-3-2)^2}=\sqrt[]{6^2+5^2}=\sqrt[]{36+25}=\sqrt[]{61} \\ \Rightarrow d(A,B)=\sqrt[]{61} \end{gathered}$

Therefore, the answer is sqrt(61)

In general,

$-(-n)=n$

Remember that

$-n=(-1)\cdot n$

Therefore,

$\begin{gathered} a-(-n)=a+(-1)(-n)=a+(-1)(-1\cdot n)=a+(-1)^2\cdot n=a+1\cdot n=a+n \\ \Rightarrow a-(-n)=a+n \end{gathered}$

Evaluate f(t)=-2t2+ 1 for f(-3).

podryga [215]

Answer:

Step-by-step explanation:

First, plug-in f(-3) into t in the function:

$f(-3)=-2(-3) +1$

Second, multiply -2 and -3 to get 6:

$f(-3)=-2(-3)+1$ ⇒ $f(-3)=6+1$

Third, add 6 and 1 to get your answer:

$f(-3)= 6+1$ ⇒ $f(-3)=7$

Answer:

y + 9 = -0.4(x-7)

Step-by-step explanation:

in slope form , we will use y - y1 =m ( x - x1) ,

which will be y + 9 = -2/5(x-7) ,

in reduced form , we have y + 9 = -0.4(x-7)
