You would use the distributive property with the negative. So the second x becomes negative, but since the 7 is already negative it becomes positive. Think of it as if you put the two dashes together you can make a plus sign.

Answer: $34.50

Step-by-step explanation:

Based on the information given in the question, since the base price of a concert ticket ticket is $30 and the handling the change is 15% is added to the brace, then the total cost of the ticket will be calculated thus:

= $30 + (15% × $30)

If p is true and ~ q is false, then p ~ q is always, sometimes, never false.
Paha777 [63]

Answer:

never

Step-by-step explanation:

The expression: ~q means "not q"

If ~q is false, then q is true

The expression:

If p is true and ~q is false

is equivalent to:

If p is true and q is true

then:

If p is true and q is true, then p -> q is <u>never</u> false (or is always true, see table attached). Or:

If p is true and ~q is false, then p -> ~q is <u>never</u> false.

Find the perimeter of the painting because that's what the frame will be:
2(5)+2(6)=P
10+12=P
22=P
Multiply 22 by 5 because the painting has a perimeter of 22 feet and each one foot will cost 5 dollars
22*5=110
The frame would cost $110
