Answer:
The Answer is multiple choice and the answer is B. Only B.
Step-by-step explanation:
Answer:
A. 15
Step-by-step explanation:
To solve this you need to compare the lengths given to you in the question statement.
Because the lines originate from a single point, they're like triangles. We can easily see a triangle AGF and a triangle ADE, right?
Both triangles are similar triangles, so we can see triangle ADE as a larger version of angle AGF.
They give you the dimension of A F and A E (through A F + F E) to establish a ratio... and they give you A G, asking for A D.
So, A F = 16, A E = 20 (16 + 4), A G = 12.
Since A D is to A G what A E is to A F, we can easily make the following cross-multiplication:
So, A D = (A G * A E)/A F
A D = (12 * 20) / 16 = 15
2(2x +2y) and <span>√(4x + 4y)^2</span>
Hi there!
nickels:19
We know that there is only nickels and dimes in his coin collection..
<u><em>1.Multiply two terms:</em></u>
<u><em /></u><u><em>·</em></u><u><em /></u>
<u><em>Then there would be 20 nickels but 1+1=2 not 2.05.</em></u>
<u><em>2.Multiply the terms:</em></u>
<u><em /></u><u><em>·</em></u><u><em /></u>
<u><em /></u><u><em>·</em></u><u><em /></u>
<u><em>3.Combine the two terms:</em></u>
<u><em /></u><u><em /></u>
Therefore, there would be 19 nickels...
