Hi.
This appears to be a right triangular prism.
You can tell, based off of how two of the shapes are shaped as.
Lets round it to the nearest ten
A 97 ====> 100
B 118 ===> 120
C 179 ===> 180
D 5091 ==> 5090
No result yet, lets round to the nearest hindred.
A 97 ====> 100
B 118 ===> 100
C 179 ===> 180
D 5091 ==> 5100
As we can see only A give the same result when we round it to the nearest hundred and nearest ten.
X = 4
7(4)+14-3(4)=30
7(-11)+14-3(-11)=-30
So, 4 is the answer because when substituted for X, it gives you 30.
.025 is the probability in decimal form.
2.5% in percent form.
The slope would be 1/17 and then you would use that slope and plug it into the y=mx+b and solve for b
