Vector QP= (-5+6, 11-4) = (1, 7)
its magnitude is QP= sqrt( 1 + 49)= sqrt (50)=5sqrt2
Answer:
A=300cm^2
Step-by-step explanation:
find both areas and subtract the inside area
if you want to multiply mixed numbers you need to turn them into improper fractions
Answer:correct answer =0
Step-by-step explanation:
Step 1
5x - (x + 3)2
Putting the coefficient of x =2 in the equaton we have
5(2) - (2 + 3)2
Solving out
5(2) - (5)2
= 10- 10
=0
Step 2
Amir's mistake was in the multiplication and wrong use of the negative sign of the bolded below
5(2) - (2 + 3)2 = 10 + (-5)2 = 10 + 25 = 35
-(5)2 cannot give 25 instead 10, so him getting a 25 and wrong use of the negative and positive made his answer wrong.
The right answer as calculated in step 1 = 0
Answer:
8
Step-by-step explanation:
b ÷ 9 when b = 72
b ÷ 9 <== substitute 72 for b, and solve
72 ÷ 9 = 8
Hope this helps!
