Answer:
1st pic- 3
Step-by-step explanation:
1st pic-
substitute the x value=0.97 into where there is an x variable.
(0.97-10)²-0.97(0.97+80)
Then you do PEMDAS-
(0.97-10)= (-9.03)² = 9.03² then (0.97+80)=80.97 which then you multiply by -0.97 which will give you 78.5409.
Now you have the equation-
9.03²-78.5409
9.03²=81.5409
81.5409-78.5409=3
3 is your final answer
Hope this helped!
