That is a math rule needed to memorize.
Answer:
x=10
Step-by-step explanation:
First square root 36 cm^2
Then you square both 8 and 6
Then you square root the sum of the two numbers.
This is called Pythagorean Theorem, which can be shown as a^2 + b^2 = c^2
2 = degree
x = variable
expression = <span>3x^2-4x+1
coefficients = 3 and -4
constant = 1</span>
0.4% can be written as 0.004 in decimal.
Step-by-step explanation:
Let the total amount she wants to save be 'a'
Starting amount = 0.4% of the total amount
= 0.4% of a
= (0.4/100) a
0.4% = 0.4/100
= 0.004
0.4% can be written as 0.004 in decimal.
a = bx + cx + d Subtract d from both sides
a - d = bx + cx Factor x from bx and cx
a - d = x (b + c) Divide both sides by (b + c)

= x Switch the sides to make it easier to read
x = <span>
