Answer:
my bad
Step-by-step explanation:
Okay. In this scenario, you are solving a proportion. Let’s make the question mark symbol an “x”. Cross multiply the values. 10 * 3 is 30. 6 * x is 6x. 30 = 6x. Now, divide each side by 6 to isolate the “x”. When you do, you get x = 5. The unknown value is 5.
Answer:
8x
Step-by-step explanation:
Because you are adding the (x+3) there you can immediately you the association property to simplify
(2x + 5x + x) + (3 - 3)
8x + 0 =
8x

Answer:
p = -3/4b -3/4
Step-by-step explanation:
Vectors are perpendicular when their dot product is zero.
A·B = p(4) +b(3) -3(-1) = 4p +3b +3
We want this to be zero, so ...
4p +3b +3 = 0
4p = -3b -3
p = -3/4b -3/4 . . . . the value of p that makes A⊥B
