Answer:
X = 3
Step-by-step explanation:
So do 7-2 which equals 5. 5 times 6 because 6 is outside of the parentheses with no symbol, so that means to multiply. That would equal 30. You want your answer to equal 6, so you would want the number inside of the parentheses to be 1, so that 1 times 6 would be 6. 2 x 3 would be sixe, and then 7-6 would equal one. 1 times 6 would be 6. So there is your answer.
Answer:
The Blue box is your answer
Step-by-step explanation:
Multiply 4, 8, and 7 and you get 224. The problem states that it should not be over 250, and 224 is not over 250. So the blue box is your best go.

Answer: u.(v+w) = -20
Step-by-step explanation:
Given;
u = -i+j
v = 10i-2j
w = -8j
v+w = 10i-2j +(-8j)
v+w = 10i-10j
u .(v+w) = (-i+j).(10i-10j)
= -1×10 + 1 ×-10
= -10-10
u.(v+w) = -20
