Answer:
The lateral surface is 120
, which agrees with the third answer option of the list.
Step-by-step explanation:
Notice that the prism has 5 equal lateral faces, which are all rectangles of eight 6". The width of the prisms can be obtained by using the fact that the perimeter of the pentagon is 20", which gives a side length of 20/5 = 4 " which is the same as the with of the lateral rectangles.
Then the lateral area of the prism is:
Lateral area= 5 (6" x 4") = 5 (24) = 120 
Answer:
g/(2 x 3)
Step-by-step explanation:
Your expression will be:
-Double 3 = multiply 3 by 2
-Divide g by the result (2 × 3)
g/(2 × 3)
Answer:
"simplify"
Step-by-step explanation:
The notion of <em>simplifying</em> an expression depends on the expression. For the one offered as an example, the simplification steps required are eliminating parentheses and combining like terms.
Other possible simplification steps include combining fractions, reducing fractions, and rationalizing denominators (eliminating surds or complex numbers).
It appears the vocabulary word that is desired in the blank is <u>simplify</u>.
Answer:
x=(-1/2) y=(3/2)
Step-by-step explanation:
y=x+2 Given
-3x=x+2 Substitute (-3x) for y
-2-3x=x Subtract 2 from both sides
-2=4x Add 3x to both sides
(-1/2)=x Divide both sides by 4.
y=x+2 Given
y=(-1/2)+2 Substitute (-1/2) for x
y=1 1/2
or
y=3/2
