1. 81.0
2. I`m trying to figure that out now I will give answers when I can
Step-by-step explanation:
Answer:
16w^2 - 24w + 9
Step-by-step explanation:
To simplify this, you would use the special product (a - b)^2 = a^2 - 2ab + b^2. We can correlate this with the given term so that,
a = 4w
and
b = 3
Now we just substitute into a^2 - 2ab + b^2
(4w)^2 - 2(4w)(3) + (3)^2
16w^2 - 24w + 9
Answer:
a) 6
b) 4.5
Step-by-step explanation:
6= 18/3 = x
4.5= 9/2 = x
19=1-5h-4h
19-1=-5h-4h
18=-9h
18/-9=h
h=-0.5
Answer:
Gradient of line A = 4
Gradient of line B = -2
Step-by-step explanation:
To solve this question, we will use the formula for gradient passing through two points and ,
Gradient (m) =
For line A,
Since, line A passes through (3, 6) and (4, 10)
Gradient of line A =
= 4
For line B,
Since, line B passes through (1, 6) and (2, 4),
Gradient of line B =
= -2
