Answer: -b - 9
Step-by-step explanation:
First, since the a cancel eachother out we are left with (4-b) + (-6-7)
Second, you want to add the -6 and -7 to get -13, so (4-b) - 13
Finally, add the 4 to the negative 13 to get (-b - 9)
Hope this helps.
Answer: 0=0 The input is an identity or it is true for all values
-3(2x+6)=-6x-18
(-3*2x)+(-3*6)=-6x-18
-6x+-18=-6x-18
0=0
Answer:
<u>The expression is 6v² + 6v - 120</u>
Step-by-step explanation:
v = Car's speed
Let's write the expression for 6 times the square of a car's speed plus 6 times the car's speed minus 120, this way:
6v² = 6 times the square of a car's speed
6v - 120 = 6 times the car's speed minus 120
Now, let's add the operator (+):
6v² (6 times the square of a car's speed) + 6v - 120 (6 times the car's speed minus 120)
<u>The expression is 6v² + 6v - 120</u>
