Answer:

20 units square

Step-by-step explanation:

do the Pythagoras theorem

a²=b²+c² ⇒ a=√b²+c²

if b is 4 and c is 2 an a is the unknown

so a=√(4)²+(2)²

a=√20

then get the rule of the area of the square

Area of the square= s²

s=a=√20 (a is the hypotenuse of the triangle and also a side in the square)

so s²=20

Area of the square=20 units square

Write an expression with the same meaning as " the result of multiplying 1/2 by a number, then subtracting 9". Please help

Musya8 [376]

Answer:

The needed expression is $(\frac{p-18}{9} )$ .

Step-by-step explanation:

Here the given expression is :

"the result of multiplying 1/2 by a number, then subtracting 9"

Let us assume the given number is p.

Firstly we multiply the given number p with (1/2).

$(\frac{1}{2} ) \times p =( \frac{p}{2} )$

Now, subtracting 9 from the result above, we get:

$( \frac{p}{2} ) - 9 = (\frac{p-18}{9} )$

So here, if the number is p, then the result is : $(\frac{p-18}{9} )$

Hence, the needed expression is $(\frac{p-18}{9} )$ .
