C.-3
x=-3
3x-15/2=4x
multiply 2 on both sides
3x-15=8x
subtract 3x from both sides
-15=5x
divide 5 from both sides
-3=x
Hello! And thank you for your question!
First move all the terms to one side:
<span>x^<span><span>2</span><span></span></span></span>−4x−9−29=<span>0
</span>
Then simplify x^2−4x−9−29:
<span><span><span>x<span><span>^2</span><span></span></span></span>−4x−38=0</span><span>
Then use the quadratic formula:
x = 4 + 2</span>√42 over 2 , 4 - 2√42 over 2
Finally simplify:
x = 2 + √42, 2 - √42
Final Answer:
x = 2 + √42, 2 - √42

Answer:
Cone Volume = (PI * radius^2 * height) / 3
Cone Volume = (PI * 6^2 * 12) / 3
Cone Volume = 452.3893421169 cubic inches

Step-by-step explanation:
Start by subtracting 2 from both side which gives you [-3x<9] then divide by -3 which gets you [x<-3] so the answer is B
let f=1
then
1^2+3(1)
=5
2(1)-1(5+1)(3)=19
hope this is the answer plz mark brillent thank you my friend
