Answer:
Second option: 4 cm and 7 cm.
Step-by-step explanation:
A Parallelogram is defined as a type of Quadrilateral, whose opposite sides are parallel and have equal lenght.
Since the opposite sides 
and 
have the same lenght, then:
Now you have to solve for "n":
Add 6 to both sides of the equation.
Subtract 3n to both sides of the equation:
Divide both sides of the equation by 2:
To know the lenght of two adjacent sides, susbtitute 
into the third side 
and into one of the the sides that are opposite to eache other. Then:
356000
i am honestly not sure if that is standard form?? but i assume it is?? i hope this helps
Answer:
16
Step-by-step explanation:
200÷25=8×2 (cups of flour) =16
Answer:
Step-by-step explanation:
Begin by dividing by 5
2x + 4 = 3
Is this written as 2^(x + 4) = 3? I think it is.
Take the log of both sides
log 2^(x + 4) = log(3)
(x + 4) * log(2) = log 3
log 2 = 0.30103
log 3 = 0.47712
(x + 4) = log2 / log3
x + 4 = 0.63093 Add 4 to both sides
x = -3.369 Rounded to the nearest thousandth
====================
If you mean the question exactly as it is written (the 4 is not part of the power)
5(2^x + 4) = 15
2^x + 4 = 3
2^x = 3 - 4
2^x = - 1
This can't be done 2 to any power should be >0.
if x>0 then this will give an ever increasing number
if xK0 then this will give an ever decreasing answer but still greater than 0.
No value will make 2^x go to something minus.
If I have misread this in some way, leave a note and I will get back to you.
