Answer:
2; -2
Step-by-step explanation:
|7-9| = |-2| = 2
|7|-9= 7 - 9 = -2
Answer:
h(4z)=4+12z / 5+4z
Step-by-step explanation:
The function h is defined by h(x)=4+3x over 5+x
This can be written as
h(x)=4+3x / 5+x
The value of the function at any time depends on the value of x. x is the independent variable. The variable,x can take any value at any time.
To find h(4z), it means that x is taking the value of 4z.
We will substitute 4z in the place of x in the function. This becomes
h(4z)=4+3×4z / 5+4z
h(4z)=4+12z / 5+4z
Answer:
A
Step-by-step explanation:
Before we can add the 2 fractions we require them to have a common denominator.
Multiply the numerator/ denominator of the first fraction by x
Multiply the numerator/ denominator of the second fraction by (x + 3)
= 
+ 
Now simplify the numerator, leaving the denominator
= 
= 
→ A
Answer:
-11/3
-1/3
The multiplicative inverse of a fraction a/b is b/a. For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one fifth (1/5 or 0.2), and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

Answer:
Below
Step-by-step explanation:
Let D be the diagonal of this square.
D forms with AB and BC a right triangle where D is the hypotenus.
We will apply then the Pythagorian theorem
●The Pythagorian theorem
● D^2 = AB^2 + BC^2
ABCD is a square, so AB=BC
● D^2 = AB^2 + AB^2
● D^2 = 2AB^2
We khow that is D= 5 cm
● 25 = 2AB^2
● 25/2 = AB^2
● 5/√2 = AB
AB is 5√2 cm
■■■■■■■■■■■■■■■■■■■■■■■■■
The perimeter is:
● P = 4AB
● P = 4×(5/√2)
● P = 20/√2
● P = 10×2/√2
● P = 10√2 cm
■■■■■■■■■■■■■■■■■■■■■■■■■■
The area is
● A = AB^2
● A = (5/√2)^2
● A = 25/2 cm^2
