Answer: k-8.4>21
Step-by-step explanation: K subtracted by 8.4 is greater than 21, so we start the equality off with our unknown variable K. Because K-8.4 is greater than 21, our symbol faces the direction of K-8.4 (symbol always faces the direction of the greater values).
Write the prime factorization of both the numerator and denominator.The prime factors of 22 are 2 and 11.
The prime factors of 14 are 2 and 7.
Rewrite the fraction so that the numerator and denominator are written as the product of their prime factors: 22 / 14 = ( 2 × 11 ) / ( 2 × 7 )Cancel out any common prime factors.
We can cancel out a 72from both the numerator and the denominator.22 / 14 = 11 / 7<span>The fraction 22/14 can be simplified to 11/7.</span>
The quadratic equation would be;
x2+15x-2=0
Working:
Assuming the area around the painting i.e the frame, has a uniform thickness, then;
Length of painting and frame = 8+x
Breadth of painting and frame= 7+x
The area from above step gives;
A= LxW
A= (8+x)(7+x)
On expanding, 56+8x+7x+x2
On simplifying,
56+15x+x2. This should be equal to 58.
58=x2+15x+56
Taking 58 to the other side,
x2+15x-2=0
Let's say we have an equation like this 7x + 3. Let x = 4. Then we will do the following:
7(4) + 3 - Replace the x with 4
28 + 3
31 - simplify down
