Hey again, you can use trigonometric ratios for this one. You are trying to find the side length opposite of angle G, when you have the adjacent side length value known. You can use TOA, or tan((opposite/adjacent)) . Tan(50) = x/10
X= 11.92 cm
Not sure if I quite understand your question. But ill assume that you're asking if 1 times 7 is positive. Or if 1x7 is positive.
1 times 7 equals 7 so it is a positive integer.
1x7 can be positive or negative depending on what x equals. If x is a negative number then the whole expression is negative. If x is postive the expression is positive.
I’m not sure but I think
F (2, -1)
G (1, -3)
H (-3, -1)
Assume the secret number is x.
"Al doubled the number and added 15 to the result. He got 51."
means 2x+15=51
solving for x:
2x+15=51
2x=51-15
2x=36
x=18
"Beverly did the same operations with their number, but in the reversed order." means she first added 15 to the number, then she doubled the result,
that is she performed the operation:
First: x+15
then: 2(x+15)
since we found x=18, then we have 2(x+15)=2(18+15)=2*33=66
Answer: 66
10-4 =6
14x10= 140
50+49= 99
49x10=490
