<h2>thank you me and brainiest me</h2>
Step-by-step explanation:
Polynomial equation Solving for 8x + 24 = 0
standard form:8(x + 3) =0
Factorization:
8(x + 3) = 0
solutions
x = −24
8
= −3
Answer:
If you are trying to solve the inequality for "x" Then your answer is, <u><em>"x>9/5" </em></u>That is the inequality form. If you are looking for the interval notation form then your answer is <u><em>"9/5, infinity" </em></u>
Step-by-step explanation:
I have checked my answers against an online Algebra solver. So my answers are 100% correct.
<u><em>PLEASE MARK BRAINLIEST</em></u>
X = 10
The triangles are similar by SAS, so we can set up a proportion of their sides.
9/(33-9) = 12/(3x+2)
9/24 = 12/3x+2
Reduce
3/8 = 12/3x+2
Cross multiply
3(3x+2) = 12*8
Distribute and multiply
9x + 6 = 96
Subtract 6
9x = 90
Divide by 9
x = 10
Check:
9/24 = 12/3x+2
9/24 = 12/3*10 + 2
9/24 = 12/30 + 2
9/24 = 12/32
3/8 = 3/8 :)
Answer:
A) 113 m²
Step-by-step explanation:
Use the formula for area of a circle.
Area of a circle = πr²
π = pi = 3.14 (rounded)
r = radius
² = the power of 2, or the radius (in this case) multiplied by itself.
Note that the radius is given, and it is 6. Plug in 6 for the radius:
A (circle) = π(6)²
First, solve the power. Multiply 6²:
6² = 6 * 6 = 36
Next, multiply 36 with π (3.14):
36 x 3.14 = 113.04
A) 113 m² is your closest answer.

Answer:
Volume = 35185.8 
Step-by-step explanation:
Recall the formula for the volume of a cone: 
Where R is the radius of the cone's circular base (in your case half of 80 km,(that is 40 km)
And h stands for the height of the cone (in your case 21 km)
We replace such in the formula and calculate its final value:

We round it to the number of decimals your problem request (let's say to one decimal) and also include the cubic units:
Volume = 35185.8
