Answer:
its 60-15(pie) sq inches
Step-by-step explanation:
The answer is -5, -5 added by 5 cancels each other out. Then when you add 4x + 8x, you get 12x. So when you do 12x= -60, you get -5.
Answer:
179
Step-by-step explanation:
39*(15/3)-16
39*5-16
195-16
179
<span>The basis of this cone is a circle with a diameter d = 16m. This information is sufficient to calculate
1. The surface of the wheel . We use the formula

<span>
2. </span><span>the radius of the wheel needed to the formula for calculating the area of a circle and the cone
d = 16m
1/2d = r = 1/2*16m = 8m

</span><span>Height , forming a cone and the radius of a circle formed triangle . Two known sides is possible to calculate the third side ( the cone ) of the Pythagorean Theorem
</span>
a = r = 8cm
b = h = 24m
c = l = ?
a² + b² = c²
r² + h² = l²
l = √ (r² + h²) = √ [ ( 8m)² + ( 24m)² ] = √ (64m² + 576m²) = √ (640 m²)= √ (8*8*10m²) = 8√10m
<span>The lateral surface of the cone
A = </span>πrl = π*8m *8√10m = 64√10πm²
The total area of the cone = <span>The base area of the side surface of +
A = 64</span>√10πm² + 64πm² = 64πm² *(√10 + 1)
Answer:
2x
Step-by-step explanation:
1.Put all of your variables together like (7x+5x+2x) and the other like numbers
2. you add up everything okay
3.when are solving dont put the ones that arent the same in the correct category
4.put both answers together and then subtract from the last number to both numbers
5.Lastly you have received your answer
