Answer:
D
Step-by-step explanation:
Because -7+6 would be -1 and two negatives have to add together to get a lesser negative number. Also YOU COULD HAVE JUST USED A CALCULATOR!!!!!!
Its d
reason is that area of a traingle is base times hight divided by 2 so H times Z divided by two =(22x7)/2==77
then you add the area of the rectangle on the bottom (W times Z )= 88
77+88=165
Hope this makes sense and I get brainiest!!

Combine like terms by adding their FACES (Coefficients)
1) 4c² - 4
2) 20m^4 + 6m
3) -6a³ - 19a² + 8a - 10
4) -10a² - 2b + 3ab³ + 4a²b² -5b^4 - 9a²b² - 12a³b + 15ab³ = -10a² - 2b + 18ab³ - 5a²b² - 12a³b - 5b^4
5) 5a³ - 5a²
Answer:
$32.10
Step-by-step explanation:
If you have sales tax, you would first convert the percentage to decimal, or 0.07. Then you would take this number, and add it to one before you multiply it by the price of the sweatshirt. This makes sure that you're not just calculating the sales tax, but the overall price of the shirt. So if you multiply:
30 x 1.07 = 32.1
Add the units, and you get $32.10
Hope this helps!
