Answer:
Step-by-step explanation:
alright, i'll help you but only if you learn from this okay?
let's start from A
4(-5)+7(2)
let's remember what is the order of operations
exponent
bracket
multiplication / division
addition / subtraction
here we have multiplication and addition:
but where is the multiplication symbol? well, sometimes multiplication symbol can be brackets
4(-5)+7(2)
so of cource multiplication first
4 times -5 = -20
7 times 2 =14
then we add
-20 + 14 = -6
B.
2(5-9)-(-3-8)
remember that inside the brackets first before multiplication
so : (5-9) = -4
(-3-8) = -11
2(-4)-(-11)
let's multiply 2 times -4 equals -8
-8 -(-11)
negative and negative equals positiove
-8 + 11 = 3
C.
(-7) ^ 2 +10(-5)
remember!, exponent first
-7^2 = -7 * -7
= 49
49 +10(-5)
then multiply 10 by -5
49 + -50
= -1
AND DONE! , hope you learn something new..
