Answer : 
Given expression is 
To make perfect square trinominal we use completing the square method
In completing the square method we add and subtract the half of square of coefficient of middle term
Here coefficient of middle term is -7
Half of -7 is 
Square of is 
=
So the expression becomes ![x^2 - 7x + [tex] \frac{49}{4}](https://tex.z-dn.net/?f=%20%20x%5E2%20-%207x%20%2B%20%20%5Btex%5D%20%5Cfrac%7B49%7D%7B4%7D%20%20)
that gives perfect square trinomial
Hence , the value of 'c' is
Answer:
15
Step-by-step explanation:
Prime factorization of the numbers:
330 = 2 × 3 × 5 × 11
75 = 3 × 5 × 5
450 = 2 × 3 × 3 × 5 × 5
225 = 3 × 3 × 5 × 5
LCM(330, 75, 450, 225)
= 2 × 3 × 3 × 5 × 5 × 11
= 4950
GCD(330, 75, 450, 225) = 15
Ok so we know that x = y+70
So y+y+70 = 300
2y+70 = 300
2y = 230
y = 115
So we know that x = y+70
do x = 115+70
X= 185
M = 24
To solve that you divide 42/7 which is 6 then you multiply 4*6 and you get 24
Integer are whole numbers like 3,18,34 and 256 rational numbers are any numbers which can be expressed as a ratio of two integers -3/4 is a rational numbers 124.45 is a rational number.in other words,rational numbers INCLUDE all integers.fraction are rational numbers
