Answer:
bottom box
Step-by-step explanation:
Answer:
3,150.
Step-by-step explanation:
- 2 · {[ 5 · ( 60 - 2 )] + 25 } · 5.
- 2 · {[ 5 · ( 58 )] + 25 } · 5.
- 2 · { 290 + 25 } · 5.
- 2 · { 315 } · 5.
- 630 · 5.
- 3,150.
These are all of the steps to completely and correctly solve this question.
Hope this helps.

Well you have to factor first factoring gives you two value that you can multiply and get you a broken down version of that
you can do it two ways using the quadratic formula to factor or if you're really good at factoring just do it mentally (2x-5)(x+1)=0
for the mental way of doing the factors just set both 2x-5 equal to zero and x+1 = to zero
2x-5=0
2x=5
x= 5/2
x+1=0
x=-1
therefore the solutions are x = 5/2,-1
but if you want to learn how to do it mentally and with the quadratic function formula
let me know
For this it would be helpful if you draw a diagram of the situation. You will see that a right triangle can be formed from the problem. We use trigonometric functions to solve. We do as follows:
sin 40 = 50/y
tan 40 = 50/x
Solving we obtain,
x = 60 mi
y = 78 mi
Hope this answers the question. Have a nice day.
