Answer:
x ≥ 3
Step-by-step explanation:
5x - 7 ≥ 8
5x ≥ 8 + 7 (You take the common terms to one side)
5x ≥ 15

x ≥ 
x ≥ 3
Answer:
1/9
Step-by-step explanation:
You can put in any 2 numbers that would make a-b=2 true, so if you use a=4 and b=2, then 3^2/3^4=1/9. This is still true with any 2 numbers that make a-b=2 true. Hope this helps!
An algebraic expression consists of variables which are represented with letters like for this case we have n, a coefficient which is indicated by numbers (e.g. 22.5, 7 and 3.4 ) and sometimes exponents Oftentimes expressions contains a number of terms which consists of those elements. To simplify an expression, we need to remember that we can only add and subtract terms that have the same base of the variable. As for multiplying and dividing, we can proceed with these operations accordingly. We simplify as follows:
<span>22.5 + 7(n−3.4)
22.5 + 7n - 23.8
7n - 1.3
The simplified expression would be written as </span>7n - 1.3.
The picture in the attached figure
we know that
area of the <span>the shaded region=area of rectangle -area of a kite
area of rectangle=(3x+x)*(x+x)----> 4x*2x---> 8x</span>²
area of a kite=(1/2)*[d1*d2]
where d1 and d2 are the diagonals
d1=4x
d2=2x
so
area of a kite=(1/2)*[4x*2x]----> 4x²
area of the the shaded region=8x²-4x²-----> 4x²
the answer is 4x²
16 x 0.42 = 6.72
