1 Solve for the unknown variable:
Burka [1]

Answer:

Approximately 6.4

Step-by-step explanation:

We can use the pythagorean thereom here, that tells us (a^2)+(b^2)=c^2. C is the hypotenuse, the side opposite from the right angle, while a and b are the other sides. We can insert 5 and 4 as a and b, and solve for c

:(5^2)+(4^2)=c^2

:25+16=c^2

:41=c^2

:sqrt(41)=6.4=c              (We square rooted both sides. 6.4 is only rounded to the nearest hundredths place.) Hope this helps!

Look at the example problem. Explain how you know 1 5/8 is little greater than 1 1/2.
natita [175]

Convert the fractions so both fractions have the same denominator. 1 1/2 is equal to 1 4/8 (1/2 * 4/4= 4/8). 1 4/8 is smaller than 1 5/8.

Can anyone explain me?​
Alika [10]

Answer:

Step-by-step explanation:

a) (a + b)² = (a + b) * (a +b)

  (a + b)³  = (a + b) * (a +b) * (a +b)

 a²- b² = (a +b) (a - b)

Here (a + b) is common in all the three expressions

HCF = (a + b)

b) (x - 1) = (x - 1)

  x² - 1  = (x - 1) * (x + 1)

  (x³ - 1) = (x - 1) (x² + x + 1)

HCF = (x -1)
