In algebra, this is: 7c <= 23
Answer:
Obtaining the area or perimeter is the easiest and basic skills in geometry, however, when combining several plane figures, composite shapes are formed, which can include: squares, circles, triangles, rectangles, trapezoids, etc.
To obtain the area or perimeter of this type of figures should analyze the figure and follow these steps:
STEP I
♦ Must identify which figures form the total.
STEP II
♦ Analyze if there are parts of the figures that you will not need, for example the sides that join two or more figures.
STEP III
♦ Obtain separately the areas and perimeters of each figure
STEP IV
♦Add the obtained in each figure.
Hope it helps you!
Step-by-step explanation:
It's important that you use the correct symbol to indicate exponentiation.
<span>f(x) = 0.4(3)x f(x) = 3(0.5)x f(x) = 0.8(0.9)x f(x) = 0.9(5)−x should be written as:
</span><span>f(x) = 0.4(3)^x f(x) = 3(0.5)^x f(x) = 0.8(0.9)^x f(x) = 0.9(5)−x.
Please double-check that last problem, as I am unsure of whether you meant 0.9^5 or (0.9)(5).
f(x) = 0.4(3)^x is definitely an exponential function.
Please try again. Do those problems that you can do an ask questions about the others.

Step-by-step explanation:
The two angles of the triangle are given as 60° and 60°
As the sum of all three angle in any triangle is always 180°, so the measure of the third angle will be: 180°-(60°+60°) = 180° - 120° = 60°
Now each angle of the triangle is 60°, it means the triangle is equilateral.
The base of the triangle is given as 12. So, the length of each side will be 12.
That means, the value of 
Now in the left right triangle.....

So, the value of 
Answer:
Option (b) is correct.
The expression is equivalent, but the term is not completely factored.
