Find the area of each figure. Round to the nearest tenth if necessary.
Shape 1: TRIANGLE
Formula: A = 1/2 x bh
1/2 x (10)(5) = 25
AREA: 25 square yards
Shape 2: RECTANGLE
Formula: A = lw
(12)(10) = 120
AREA: 120 square yards
Sum (ADD)
25 yd^2 + 120 yd^2 = 145 yd^2
The area of the composite figure is 145 yd^2
Which of the following expressions are equivalent (equal) to 3(2x - 7)
Answer:
6x - 21
Step-by-step explanation:

3 × 2x = 6x
3 × -7 = -21
Combine:
6x - 21

Find the value of x in the isosceles triangle shown below.
Answer:
sqrt of 41, or A
Step-by-step explanation:
You can cut the iscosles triangle into 2 right triangles as shown on the image, and the base of each will be 4, and the height 5.
The hypotenuse on a right triangle is the square root of the base squared added with the height squared, which would be 16+25, or 41. therefore, X is the sqrt of 41
Answer:
A. x = square root of 41

Jordan flipped a coin 218 times. Which of the following would be a good estimate of the number of times the coin landed on heads?
A. 168
B. 104
C. 209
D. 34
Ans: (1/2)218 = 109
----
Closest to that is 104
Answer:
B. 104
Step-by-step explanation:
It would make the most sense if it were somewhere in the middle since flipping a coin has a 50% chance of being heads.
B. 104 is closest to the absolute middle of 218, therefore, it would be the most accurate.

Answer:
It is a reflection across the y axis
Step-by-step explanation:
The reflection of point (x, y) across the x-axis is (x, -y).
The reflection of point (x, y) across the y-axis is (-x, y).
Since (-4, -2.4) becomes (4, -2.4) The x values changes sign. It is a reflection across the y axis
For the equation, determine whether the equation is true for all, some, or no values of x.
Explain how you know.
Answer:
You can check if an equation is true for all some or no values of x by simply to try and solve the equation if you get something like x = x, then the equation is true for all, if you get a specific answer like x=3, then it is true to some values, in simple terms. Try and solve the equation there is no other way to check unless you solve, I don't know if there is another way but this is just my intution.

f(g(x))=3+cos2x
g(f(x))=g(3+cosx)

g(f(x))=6+2cosx
where,
f(g(x))=g(f(x))
3+cos2x=6+2cosx
