Answer:
b) 123
Step-by-step explanation:
<h3>Given:</h3>
PQRS is a rectangle.
PS = 5cm
PQ = 12cm
<h3>To Find:</h3>
The length of qr ,sr and the two diagonals pr and qs.
<h3>Solution:</h3>
Opposite sides of a rectangle are equal.
QR = PS = 5cm
SR = PQ = 12cm
By using Pythagoras Theorem, we get
PR = √PS^2 + SR^2
or, PR = √25 + 144
or, PR = √169
or, PR = 13cm
Diagonals of a rectangle are equal.
QS = PR = 13cm
<h2>Answer:</h2>
QR = 5 cm
SR = 12 cm
PR = 13 cm
QS = 13 cm
Answer:
4y+q(3-5q^2)
Step-by-step explanation:
common taking from 3q-5q^3
Answer:
The number is 6
Step-by-step explanation:
Let's say that the reciprocal of the number is x
1/2 + 3 = 1
3x = 1/2
divided both sides by 3
x = 1/6
Since x is the reciprocal of the number, flip 1/6 and you will get 6/1
6/1 is really just 6 so that's your answer.
Hope this helps :)
