Value of expression 
is 22 .
<u>Step-by-step explanation:</u>
Here we have the following expression to solve :
8÷2*5+(6-4)
⇒ 
⇒
But 8 = 4(2) , So
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore, Value of expression is 22 .
21 because you can do 84 divided by 21 or you can also do 4 times any number that sounds like it would =84. (Stick with option 1 unless you are super confused)
Answer:
x=2 , x=(-1)
Step-by-step explanation:
y=x^2+3----------1
y=x+5-------------2
1=2
x^2+3 = x+5
x^2-x-2=0
(x-2)(x+1)=0
x=2 , x=(-1)
180 is 6x larger than 30, and 30 is 6x larger than 5. so y is 6x larger than x, and n is 30
