Answer:
x=42
Step-by-step explanation:
1. Multiply 7 to both sides of equal sign
84=2x
2. Divide by 2
x=42
3,256,423,865 rounded to the nearest million is 3,256,000,000. How I know is that the 4 in the hundred thousands place is lower than 5. So the 6 would of stayed the same and the rest of the number behind 4 would of been 0, including the 4.
Answer:
A = 10m^2
Step-by-step explanation:
Divide the figure into 3 smaller figures (a triangle, a rectangle, and a square). Then, solve for the area of each composite figure.
A of triangle = (2 x 2)/2 = 2
A of rectangle = 4 x 1 = 4
A of square = 2 x 2 = 4
A of figure = 2 + 4 + 4 = 10m^2
Another way to solve this is to find the area of the entire figure plus the area of a triangle. This would look like A = 3 x 4 = 12. But, since the extra triangle area is included, we must subtract this from the total area.
A of triangle = (2 x 2)/2 = 2
A of figure = 12 - 2 = 10m^2
