Answer:x=4 is not a root
Step-by-step explanation:
Asssuming blanks are plus
5(x+1)=4(x+8)
distribute
a(b+c)=ab+ac
5(x+1)=5x+5
4(x+8)=4x+32
5x+5=4x+32
minus 4x from both sides
x+5=32
minus 5 from both sides
x=27
Step-by-step explanation:
a^2+b^2=c^2
3^2+9^2 not equal to 12^2
Answer:
(-1,3)
Step-by-step explanation:
Thus;
When (-1,3) is placed in the relation 3x + y =0,the answer will be zero.
<h3>Calculations</h3>
Let;
x= -1
y= 3
3(-1) + 3 =0
-3 + 3 = 0
