<u> Equation:</u>
x(x - 5) + 3(x + 5)
<u>Steps:</u>
x(x - 5) + 3(x + 5)
<u>Expand:</u>
x(x - 5 ): x^2 - 5x
x^2 - 5x + 3(x + 5)
<u>Expand:</u>
3(x + 5): 3x + 15
x^2 - 5x + 3x + 15
<u>Add Similar Elements: </u>
-5x + 3x
= -2x
Answer x^2 - 2x + 15 Doesn't Factor
Hope that helps!!! : )
Answer:
30.
Step-by-step explanation:
6 = 2 * 3
5 = 5
LCM = 2 * 3 * 5 = 30.
∠SCD =150 and ∠BCD=174 (Given)
∠BCS + ∠SCD = ∠BCD (Segment Addition Postulate)
∠BCS + 150 = 174 (Substitution)
∠BCS = 24 (Subtraction Property of Equality)
Answer: 24
