Answer:
1. 4x + 6
2. -15x + 11
5. -x + 4
6. -4x + 7
9. 5x - 2
12. x + 16
Step-by-step explanation:
Remove the parenthesis for each one so everything's out in the open. Next, you group like terms. The numbers with variables on one side, and the other numbers on the other side. For example:
x + 3x - 2 + 8
Then, you combine like terms:
4x + 6
That's mostly how you do each one.
You answer is 4.7
Explanation
I assume that the shaded region is the area inside of rectangle and outside the circle
so
The shaded region is equal to the area of rectangle minus the area of circle
step 1
Find the area of rectangle
The area of rectangle is equal to multiply the length by the width
A= (3)-(11)=33 cm^2
tep 2
Find the area of the circle
The area of the circle is
A=\pi r^{2}
we have
r=3\ cm
\pi =3.14
substitute
A=(3.14)(3^{2})
A=28.26\ cm^{2}
step 3
Find the area of the shaded region
33-28.26=4.74\ cm^{2}

So an equation of any line is y=mx+b.
We know that the m, or slope, equals 3.
y=3x+b
Now we find the b, or the y-intercept, by substituting the x and y values into their places.
4=3*1+b
4=3+b
b=1
Now that we have the y-intercept, we just substitute the m and b into the equation and receive our final answer:
y=3x+1
Answer:
<A = 27 degrees
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
Tan A = opp side / adj side
Tan A = 2/4
Tan A = 1/2
Taking the inverse tan of each side
tan^-1 ( tan A) = tan ^-1 (1/2)
A =26.56505118
Rounding to the nearest degree
A = 27
