Answer:
38 cm^2
Step-by-step explanation:
The surface area of a rectangular prism is
SA = 2(lw+wh+lh) where h is the height l is the length and w is the width
SA = 2( 3*1 + 3*4+4*1)
= 2(3+12+4)
= 2(19)
= 38 cm^2
I think its B
I might be wrong
Answer:
180
Step-by-step explanation:
x+10, 2x+15, and 3x-13. what are the degree measures of the angles of the triangle? The sum of the measures of the angles of triangle = 180 degrees.
You can use sigma notation to represent an infinite series. For example, ∞∑n=110(12)n−1 is an infinite series. The infinity symbol that placed above the sigma notation indicates that the series is infinite. To find the sum of the above infinite geometric series, first check if the sum exists by using the value of r .
Answer:The first one and the thrid one
Step-by-step explanation:
The second one isn't a linear one because number 5 represents 3,1... and that number is down the y's line. That means it has to go down again but without decreasing, stopping the function to become a linear one and becoming a non constant one.
I hope I'm being helpful...
