Answer:
Simplified expression: (2r+16)(2r+16)
if you need to combine like terms it would be 4r+32
Step-by-step explanation:
to distribute you multiply whatever is outside the parenthesis with everythign inside. 2*r= 2r, 2*8= 16
(2r+16)(2r+16)
and if you want to combine like terms it would be
4r+32
since you add whatever goes together (whole numbers +whole numbers, numbers with variable+ numbers with variable)

[tex]2 {}^{2x} = y[/tex]
now,

Each side of a square patio is 10.5 feet. The patio is made up of 1.5 foot by 1.5-foot square stones. What is the number of stones in the patio? Look at the solution below.
Does it include all the steps needed to solve the problem? Explain
10.5 x 10.5 = 110.25
110.25 ÷ 1.5 = 73.5
Answer:Yes
Step-by-step explanation:
The solution provided is complete and includes all the steps needed to solve the problem.
The first step is to calculate the area of the square patio by multiplying the length of one side by itself:
10.5 x 10.5 = 110.25.
The second step is to divide the area of the patio by the area of each individual stone to determine the number of stones needed:
110.25 ÷ 1.5 = 73.5.
Since it is not possible to have a fraction of a stone, the answer should be rounded up to the nearest whole number, which is 74.
Therefore, there are 74 stones on the patio.

pamelia is 9 years younger than jiri. The sum of their ages is 55. What is Jiris age?
Answer: 32
Step-by-step explanation: since Jiri is 9 years older, you set an equation where x (Pamelia age) + 9. So the equation is 55= x + (x+9). You subtract 9 from both sides, then divide 46 by 2 to find the Pamelia age. To find Jiri’s age, add 9 to 23 (Pamelia age).

Step-by-step explanation:
We want to find [tex]\theta[/tex] such that [tex]\theta=\sin^{-1}(1.1976)[/tex].
We can take the sine of both sides of the equation to get[tex]\sin(theta)=\sin(\sin^{-1}(1.1976))=1.1976[/tex].
We know that the range of the sine function goes from -1 to 1 inclusive, so there is no value [tex]\theta[/tex] such that [tex]\sin{\theta}>1[/tex].

BC has a midpoint at M(6, 6). Point C is at (2, 10). Find the coordinates of point B.
Answer:
The coordinates of B are (10,2)
Step-by-step explanation:
Hi there!
We know that BC has a midpoint M, with the coordinates (6,6), and the endpoint C, with coordinates (2, 10)
We want to find the coordinates of point B
The midpoint formula is [tex](\frac{x_1 + x_2}{2}, \frac{y_1+ y_2}{2})[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2 , y_2)[/tex] are points. In this case, the point C has the values of [tex](x_1, y_1)[/tex], and B has the values of [tex](x_2 , y_2)[/tex]
We know that coordinates of M equal [tex](\frac{x_1 + x_2}{2}, \frac{y_1+ y_2}{2})[/tex]
In other words,
[tex]\frac{x_1 + x_2}{2} = 6\\ \frac{y_1+ y_2}{2}=6[/tex]
Let's plug 2 for [tex]x_1[/tex] and 10 for [tex]y_1[/tex]
So:
[tex]\frac{2 + x_2}{2} = 6\\ \frac{10+ y_2}{2}=6[/tex]
Multiply both sides by 2
[tex]{2 + x_2} = 12\\{10+ y_2} =12[/tex]
Subtract 2 from both sides in the first equation to find the value of [tex]x_2[/tex]:
[tex]x_2=10[/tex]
Now, for the second equation, subtract 10 from both sides to find the value of [tex]y_2[/tex]
[tex]y_2=2[/tex]
Now substitute these values for [tex](x_2, y_2)[/tex]
[tex](x_2, y_2)=(10,2)[/tex]
So the coordinates of point B are (10, 2)
Hope this helps!
