Answer:
the second answer is correct
Step-by-step explanation:
an inscribed angle is half of the intercepted arc
First factor x^2+13x+36 using the AC method. Then if any individual factor on the left side of the equation is equal to zero the whole expression will equal zero. After that set x+4 equal to zero and solve for x and do the same for 9. Lastly your answer is all the values of (x+4)(x+9)=0 true.
4x^2 = 100...divide both sides by 4
x^2 = 100/4
x^2 = 25....take the sqrt of both sides, eliminating the ^2
x = sqrt 25
x = 5 <===
Let cost of the sculpture before increase was $x.
Cost increases by 30%
so new cost = x + (30% of x) = x+0.30x = 1.30x
Given that cost after increase is $520 so both will be equal and we get:
1.30x=520
x=520/1.30
x=400
So the final answer is $400.
The square root of 6 is about 2.449489
The square root of -5 is about -2.23606
50/20=2.5
2.43
1. -√5 2. 2.43 3. √6 4. 50/20
hope this helps:)
