It would be -2x2+11x-4 good luck
Answer:
18.84
Step-by-step explanation:
because the radius is 3, the diameter is 6. And the circumference is C=pi(d).
In this case, C=3.14(6), and 3.14*6=18.84
Answer:
<h3>The answer is option A</h3>
Step-by-step explanation:
Surface area of a pyramid =
area of base + area of triangular faces
Since it's a square based pyramid
It's surface area is
area of base + 4( area of one triangular face)
Since the square has equal sides
<u>For square base </u>
Area of a square = l²
where l is the length
From the question l = 5
So we have
Area of square base = 5² = 25ft²
<u>For one of the triangular face</u>
Area of a triangle = ½ × base × height
base = 5
height = 6
Area = ½ × 5 × 6 = 15ft²
So the surface area of the pyramid is
25 + 4(15)
= 25 + 60
We have the final answer as
<h3>Surface area = 85 ft²</h3>
Hope this helps you
Answer:
-x= -14
Step-by-step explanation:
3(x+2)-4=4(x-3)
3(x+2)=3x+6
3x+6-4=3x+2
3x+2=4(x-3)
4(x-3)=4x-12
3x+2=4x-12
3x-4x=-1x
-12-2=-14
-x=-14
