Answer:
Step-by-step explanation:
6f + 9g = 3g + f
6f - f = 3g - 9g
5f = - 6g
So, it's only x - 3 = 13, or x = 16! Hope it helps
Surface Area is the area of each face added together. For this question lets find the area of one triangle first.
Area of a triangle is base*hight/2, so 6*7/2=21. That was the area of one triangle. We have 4 traingle so we multiply that by for. 21*4=84.
Now, lets find the area of the squre. area of square is side*side or side^2.
So we multiply 6*6=36. that is the area of the square.
To find the surface area, we must add Area of Triangles+Area of Square.
so, 84+36=120
So the surface area is 120

Answer: 0.9999</h3>
Explanation:
Having a 1% increase means we go from 100% to 100%+1% = 101% which converts to the decimal form 1.01; note how you move the decimal point two spots to the left to go from 101% to 1.01
A 1% decrease means we go from 100% to 100%-1% = 99% = 0.99
Multiplying 1.01 and 0.99 leads to 1.01*0.99 = 0.9999
Since 0.9999 = 99.99%, this means we have a 100% - 99.99% = 0.01% decrease overall.
Note: the order of the decrease and increase doesn't matter. You could do the decrease first, then the increase, or vice versa.
