Answer:
∠DCF = 129°
Step-by-step explanation:
We assume that line CE is between lines CD and CF.
The angle sum theorem applies:
∠DCF = ∠DCE +∠ECF
∠DCF = 75° +54°
∠DCF = 129°
Answer:
A
Step-by-step explanation:
We assume this playground is a rectangle. The area of a rectangle is of the form: A = lw, where l is the length and w is the width.
Here, the length is l = x and the width is w = x + 3. So, plug these in:
A = lw
A = x(x + 3)
Expand this out:
A = x² + 3x
The answer is thus A.
Your correct answer is option B
Answer:
33.32
Step-by-step explanation:
<h2><u>can use cross multiplication </u></h2>
20 : 34
19.6 : x
20x = 19.6 * 34
20x = 666.4
x= 666.4/20
x=33.32
<u>area = 33.32 </u>
The answer is D. 9(y + 3) and 27 + 9y because 9(y + 3) when expanded is 9y + 27. I hope this helps!
