Answer:
-41
Explanation:
The equation you have is 3 × (-9) + (-2) × 7
(i think, i hope i read that right)
Not sure if you've heard this before, but you need to use PEMDAS:
P - Parenthesis
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
Since we don't have any parenthesis or exponents, we go straight to multiplication.
You need to multiple 3 × (-9) and (-2) × 7
Multiplying the first two, 3 × (-9), gives you -27.
Multiplying the second two, (-2) × 7, gives you -14.
Now you are left with -27 + (-14).
Once you add those two, you get -41.
hope this semi-helped!
