The difference of 5 and 2
5-2 <===== now multply it by 6
6 x (5-2)
Answer:
k = 15
Step-by-step explanation:
∵ x² - 8x + k = 0 ⇒ has two roots x1 and x2
∵ ax² + bx + c = 0 has two roots
∴ The sum of roots = -b/a and the product of them = c/a
∵ a = 1 , b = -8 and c = k
∴ x1 + x2 = -(-8)/1 = 8
∴ x1 + x2 = 8 ⇒ (1)
∵ 3x1 + 4x2 = 29 ⇒ (2)
Multiply (1) by -4
∴ -4x1 - 4x2 = -32 ⇒ (3)
Add (2) and (3)
∴ -x1 = -3
∴ x1 = 3
By substituting value of x1 in (1)
∴ 3 + x2 = 8
∴ x2 = 5
∴ The roots are 3 and 5
∴ c/a = 3 × 5 = 15 ⇒ (a = 1)
∴ c = 15
∴ k = 15

Answer:
x = 4
Step-by-step explanation:
the segment inside the triangle is an angle bisector and divide the opposite side into segments that are proportional to the other two sides, that is
= 
= 
= 
( cross- multiply )
2x = x + 4 ( subtract x from both sides )
x = 4
Answer:
We found the factors and prime factorization of 28 and 26. The biggest common factor number is the GCF number. So the greatest common factor 28 and 26 is 2.
