Answer:
the answer is x=-5. a negative times a negative is a positive.
Answer:
126∏
Step-by-step explanation:
area = 2 * area of the circle + area of the rectangular surface
area = 2 * r² * ∏ + 2 * r * ∏ * h
area = (2 * r² + 2 * r * h) * ∏
area = (2 * 7² + 2 * 7 * 2) * ∏
5.637 x 10^3 that’s all iv got
Answer:
x = +5
Step-by-step explanation:
The triangles ADB and BDC are similar. Thus it is possible to write an equation of ratios and solve it for x:
x 10
----- = -------
10 4x
Cross-multipying, we get:
4x^2 = 100, which yields x = +5
