Answer:190
Step-by-step explanation:
area of triangles is 5*3=15
15+15=30
rectangles are (5*10)*2+(6*10)=160
160+30=190
8.9-3.3j=-2.2j+2.3
add 3.3j to both sides
8.9=1.1j+2.3
subtract 2.3 from both sides
6.6=1.1j
divide both sides by 1.1
6=j
Answer:
If it is 48 cm long, then it should be around 25 cm wide.
Step-by-step explanation:
10/19=x/48 so you cross multiply and get 19x=480 then you divide both sides by the 19x and you should get x=25e7 or just 25 cm

Rational
Step-by-step explanation:
A rational number includes any whole number, fraction, or decimal that ends or repeats. An irrational number is any number that cannot be turned into a fraction, so any number that does not fit the definition of a rational number.
Answer:
n = 3
Step-by-step explanation:
9{n+2(n-2)} = 45
Start with the numbers on the inner most pair of parentheses
Multiply (n-2) by 2
9[n+2n-4] = 45
Add what is inside the parentheses
9[3n-4] = 45
Multiply
27n-36 = 45
Add 36 to both sides
27n = 81
Divide both sides by 27
n = 3
Hope this helps!
