Okay, your answer would be 247.5mm² hope that helped
Answer:
39=22
28-6 equal to 22 so 39= 22
Answer:
Q = (P-9)/2
Step-by-step explanation:
Answer:
1/6
Step-by-step explanation:
It's 1/6 because the only multiple of 5 in a die is 5, so it will be 1/6.
To find out if they are parallel we need to see if the gradient is the same, to do this we need to get y in terms of x:
assuming the first equation is x+y+7=0
y=-x-7
and
y=x-3
The gradient is the coefficient of x (the number infront of x)
For equation 1 the gradient is -1, and for number 2 it is 1, therefore they are not parallel.
However to check if they are perpendicular we need to see if their gradients multiply to equal -1.
-1*1=-1 therefore they are perpendicular
