Answer:
2.84×10²
Step-by-step explanation:
0.0284×10⁴
Move the decimal point 4 places to the right.
284
Now write in scientific notation by moving the decimal point 2 places to the left, behind the 2.
2.84×10²
<span> 4x+7=5
subtract 7 on both sides
4x = -2
divide both sides by 4
x = -2/4
simplify
x = -1/2</span>
Given that the two cone are similar, then
3/7 = x/5
7x = 15
x = 15/7
First answer is (-2,2) second answer is (4,2)
The answer is A. Hope this helps
