Answer:
4x^2+24x=4
Step 1:
make the coefficient of x² as 1, divide both sides by 4
x² +6x =1
Step 2:
take half of coefficient of x, square it and add it to both sides
half of 6 is 3 and 3²=9, so add 9 to both sides
x² +6x+9=1+9
x²+6x+3²=10
(x+3)²=10
now when we take square root we will get both + and - √10 on right side
x+3= +√10
x+3=-√10
solving for x
x=+√10-3
Step-by-step explanation:
Answer:
z in terms of x is
Step-by-step explanation:
We are given:
We need to find z in terms of x
First we can find value of y from x =2y-5
Now, we can put value of y in to find z in terms of x
So, z in terms of x is
0.2 1/2 because it is closes to two $o yeah.
