Answer:
$40.60
Step-by-step explanation:
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

Answer:
26 mm
Step-by-step explanation:
A=wl= 42 mm²
l=7, w= 42/7= 6 mm
P=2(l+w)= 2(7+6)= 26 mm
