Answer:
Scale using for plan ⇒ 1 m = 4 cm
Step-by-step explanation:
Given:
Actual length of wall = 4 m
Segment of wall = 16 cm long
Find:
Scale using for plan
Computation:
Actual length of wall = Segment of wall
4 m = 16 cm
1 m = 16 / 4 cm
1 m = 4 cm
Scale using for plan ⇒ 1 m = 4 cm
Yes, considering the fact that the number line can contain any number.
Step-by-step explanation:
We khow the sum and the product of the zeroes of this quadratic polynomial
Here is a trick :
when we khow the sum S and the product P ofvtwo numbers we can find them by solving :
x²-Sx+p=0
here S= -8 and P=12
so:
x²+8x+12=0
Let Δ be the discrminant of this equation: a= 1 , b= 8 and c=12
Δ= 8²-4*12 =16
the zeros are:
(-8-4)/2= -6
(-8+4)/2 = -2
verify:
-6+(-2)= -8
-2*(-6)= 12
now the polynomial quadratic is:
(x+6)(x+2)
