In geometry, the segment addition postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.
Let's simplify step-by-step.
−4x−3(3x6)+8(2.5x+3.5)
Distribute:
=−4x+−3(3x6)+(8)(2.5x)+(8)(3.5)
=−4x+−9x6+20x+28
Combine Like Terms:
=−4x+−9x6+20x+28
=(−9x6)+(−4x+20x)+(28)
=−9x6+16x+28
Answer:
=−9x6+16x+28
Answer:
69.08
Step-by-step explanation:
2×3.14=6.28
6.28×11=69.08

<span>
Bradley made a house for his dog, Bowser, out of wood with a cube base and a triangular prism top. The dimensions of the dog house are a = 2 feet, b = 1 foot, and c = 1.4 feet.</span><span>
If Bradley plans to paint the outside of the dog house blue, not including the bottom, how many square feet of paint will he use?the picture in the attached figure
</span>
we know that
surface area of the figure=surface area of cube+surface area of triangular prism
surface area of cube=4*a²----> 4*2²-----> 16 ft²
surface area of triangular prism=2*[a*c]+2*[a*b/2]---> 2*[2*1.4]+[2*1]
surface area of triangular prism=5.6+2----> 7.6 ft²
surface area of the figure=16 ft²+7.6 ft²----> 23.6 ft²
the answer is23.6 ft²
Answer:
C. 2:5
Step-by-step explanation:
You can divide both side of the ratio 20:50 by 5 which leaves you with 4:10. You can simplify it again by dividing it by 2 and get 2:5
