I'll help with 10,
A=b×h÷2 is your equation so I would substitute in the six and eight next.
The base is 6 and the height is 8 so 6×8÷2=A
Then I would do 6×8=48, 48÷2 is 24.
The area is 24 cm squared.
Answer:x+y=8
Step-by-step explanation:the line has an x intercept that is in between the points
The lest common multiple of 19 and 14 is 266
hope this helped
Answer:
k = 5
Step-by-step explanation:
I will assume that your polynomial is
x^2 - 3x^2 + kx + 14
If x - a is a factor of this polynomial, then a is a root.
Use synthetic division to divide (x - 2) into x^2 - 3x^2 + kx + 14:
2 / 1 -3 k 14
2 -2 2k - 4
-------------------------------------
1 -1 (k - 2) 2k - 10
If 2 is a root (if x - 2 is a factor), then the remainder must be zero.
Setting 2k - 10 = to zero, we get k = 5.
The value of k is 5 and the polynomial is x^2 - 3x^2 + 5x + 14
