So in the photo, I was trying to do an order of operations problem with photomath. But I don’t like to cheat without understandi

ng something, and here I don’t understand.
Photomath subtracted 15-3 first because it’s in para thesis. But there is a 2 next to the parentheses so aren’t you supposed to distribute the 2 to the 15 and 3 and THEN subtract? Or do you not distribute? If so, why?

Answer:

the answer of the complete equation is 0

Step-by-step explanation:

first you multiply by 2 all in the parenthesis, 2(15) and 2(3) you got a 30. Then you do the exponents 3(3) is 9

so you got like this= 30-6+9(4)

You multiply 9 and 4=

30-6+36

and the answer is 0

Hey surveyor is measuring the distance across a small lake. He has set up his transit on one side of the lake 150 feet from a Pi
AleksAgata [21]

Answer: 87 feet

Step-by-step explanation:

The angle between the pilling is 60°

The adjacent side of the right angle is 150

So let the distance between the pilling be y, that is opposite side.

Opposite / adjacent = tan (60°)

y / 150 = tan (60)

y × tan (60°) = 150

Divide both side by tan (60°)

y = 150 / tan (60°)

y = 150 / 1.7321

y = 87 feet

Bethany says that 3x+6+x and 3(x+2) and equivalent expressions. She used substitution to support her answer. Explain what Bethan
Vinvika [58]

She forgot about the final x at the end, because the first expression is 3x+6+x, and the second one is 3(x+2). The second one expands to 3x+6, but it doesn't have the final term at the end.

Also, 3 is not really a factor of x (technically it could be because x in unknown, but in terms of like terms and stuff it isn't) so you can't take a 3 out of x (unless you leave it as 1/3x I guess).

Anyway, yeah she forgot about the final x and therefore the factor she took out is incorrect anyway. She also could've simplified the first expression so that it became 4x + 6
