All faces are rectangles.
Each two opposite faces are congruent and have the same area.
Two faces measure 20 cm by 7 cm.
Two faces measure 20 cm by 15 cm.
Two faces measure 15 cm by 7 cm.
total surface area = 2 * 20 cm * 7 cm + 2 * 20 cm * 15 cm + 2 * 15 cm * 7 cm
total surface area = 280 cm^2 + 600 cm^2 + 210 cm^2
total surface area = 1090 cm^2
The answer would be A. because 30 is how many she did but then h is the variable we are trying to figure out like the h can be any letter it just is there to show that the "person" does not know what the number is. Hope this helped!
Answer:
x = 3/7 or 3 over 7
x=-2
g=36
Step-by-step explanation:
<em>7x=3</em>
1. divide both sides
(7x÷7 = 3÷7)
2.any expression divided by itself equals 1.
x=3÷7
3.write the division as a fraction
x= 3/7
4.solution is x=3/7 or x= 0.248571
<em>x</em><em>=</em><em> </em><em>-2</em>
1.divide both sides by 2.
(÷2(x+1)=-2÷2)
x+1=1
2.move constant to the right hand side and change its value.
x= -1-1
3.Calucate the difference.
x=-2
<em>2</em><em>/</em><em>9</em><em>g</em><em>=</em><em>-8</em>
<em>1</em><em>.</em><em> </em>multiple both sides of the equation by 9/2.
2. Reduce the numbers with the greatest common factor {9},then reduce the greatest common factor {2}.
g= -9x4
3.mutlipy the numbers
g=-36
Answer:
188,582 fewer people attended the 2010 olympics to the 2006 olympics.
Step-by-step explanation:
Add all of the 2010 matches then subtract from 2006 total. You will get a negative number. Hope I helped!:-)
