Aleksandr-060686 [28]
<h3>Answer:  9/50</h3>

Explanation:

Any percentage converts to that number over 100.

So 18% would convert to 18/100

We then reduce the fraction by dividing each part by the GCF 2

18/2 = 9

100/2 = 50

The fraction 18/100 fully reduces to 9/50

Mashutka [201]
Let
x--------> original length side of a square

we know that
area rectangle=length*width
area=126 in²
length=(x+8)
width=(x-3)
so
126=(x+8)*(x-3)------> x²-3x+8x-24=126----> x²+5x-150=0

using  a graph tool------> to resolve the second order equation
see the attached figure
the solution is
x=10 in

the answer is
the original length side of a square is 10 in

(3a2 + 2ab + 2b) + (5a2 − 3ab + 9)
ivann1987 [24]

Step-by-step explanation:

\tt{(3 {a}^{2}  + 2ab + 2b) + (5 {a}^{2}  - 3ab + 9})

~While adding , the sign of each term of second expression remains same. So, Remove the unnecessary parentheses :

⤑ \tt{3 {a}^{2}  + 2ab + 2b + 5 {a}^{2}  - 3ab + 9}

~Like terms are those which have the same base. Combine the like terms :

⤑ \tt{3 {a}^{2}  + 5 {a}^{2}  + 2ab - 3ab + 2b + 9}

⤑ \sf{8 {a}^{2}  - ab + 2b + 9}

\red{ \boxed{ \boxed{ \tt{ ⟿ Our \: final \: answer : 8 {a}^{2}  - ab + 2b + 9}}}}

Hope I helped ! ツ

Have a wonderful day / night ♡
