We have been given an expression 
. We are asked to find the solution to our given expression expressed as scientific notation.
Let us simplify our given expression.
Using exponent property 
, we will get:
Now to write our answer in scientific notation, we need our 1st multiple between 1 and 10. So we will rewrite our expression as:
Therefore, our required solution would be .
Answer:
11 m and 7 m
Step-by-step explanation:
Width = x
Length = x+4
P=2L+2W
P=2(x+4) + 2x=4x +8
36 = 4x + 8
4x = 28
x=7 Width
x+4=7+4=11 Length
2.7 = 27/10
27/10 = x/12
cross multiply
10x = 324
divide both sides by 10
x = 32.4
Reflect over the line y=-x
Answer:
area of trapizoid=49 unit^2
Step-by-step explanation:
area of trapizoid=0.5(x+y)h
where, x=parallel side=3units
y=parallel side =11 units
h=distance between two parallel sides
area of trapizoid=0.5(x+y)h..............(1)
put x=3 units,y=11 units and h=7 in equ (1)
area of trapizoid=0.5(3+11)7
area of trapizoid=
area of trapizoid=49 unit^2 answer
