Your answer is 19/28

First you find common denominators

1/4 and 3/7 both have 28 as a common denominator

Multiply the denominators to get the same denominator 1/4 by 7= 7/28 and 3/7 by 4= 12/28

Add that and you get 19/28 and it stays like that because you can’t simply it

Answer:

1/4 + 3/7 = 19/28

Step-by-step explanation:

Step 1: Find common denominator

Common denominator of 7 and 4 is 28 (since 7 × 4 = 28)

Step 2: Multiply fractions by the factor (equivalent to 1) that will bring each denominator to 28

1/4 × 7/7 = 7/28

3/7 × 4/4 = 12/28

Step 3: Simply add the newly-converted fractions

7/28 + 12/28 = 19/28

This fraction cannot be simplified, so the final answer is 19/28.

Help with Area of a sector

Maurinko [17]

Area 1 = 175.84
area 2 = 156.30

area 1: A=(pi)r^2 x 140/360
in this case we would use the degree of the entire circle and the degree of the sector since it is not given.

area 2: A=(pi)r^2 x 280/360
in this case we would use the degree of the entire circle and the degree of the sector since it is not given.

Answer:

Step-by-step explanation:

$x^2+8x=38\\\\x^2+8x-38=0\\\\\Delta=8^2+4*38=216=6^3\\\\x=\dfrac{-8-6\sqrt{6} }{2} \ or\ x=\dfrac{-8+6\sqrt{6} }{2}\\\\x=-4-3\sqrt{6} \ or\ x=-4+3\sqrt{6}\\\\a=-4\\b=3\\c=6\\$
