Answer:
each measure 120
Step-by-step explanation:
<span>"Five times a number added to -4"
5x + (-4)
</span>
<span>subtracted from...
"twice the sum of eight times the number and 7"
2(8x + 7)
5x - 4 - 2(8x + 7)
distribute the -2
5x - 4 - 16x - 14
combine like terms
</span><span>
-11x - 18
</span>
When adding and subtracting with exponents....combining like terms....exponents are not added/subtracted...but coefficients are.
example : 2b^2 + 3 + 3b^2 = 5b^2 + 3
but keep in mind, they have to be like terms to be able to add and subtract them...for instance 2b^2 + 3b^3...u cannot add/subtract them because they are not like terms.
I am not sure if this is right , but I tried . I hope I helped !
Your answer is D . Hope I helped :) !
