Answer:

  • 93 in²

Step-by-step explanation:

<u>Given triangular prism with:</u>

  • a = 1.5 in, b = 2 in, c = 2.5 in, l = 15 in

<u>Total surface area is:</u>

  • A = Pl + 2B, where P is the perimeter of base, B is area of base

<u>Considering all given values we have:</u>

  • A = (1.5 + 2 + 2.5)*15 + 2*(1/2*1.5*2) = 93 in²

babymother [125]
If you want to know what is the number of m so first you can add 2 on both sides of equation like : 13 = 5m - 2 
                            +2        +2 ⇒ 13 + 2 = 5m ⇒ 15 = 5m ⇒ 15/5 = m ⇒ 3=m :))
i hope this be helpful

Find the equation in slope-intercept form of the line parallel to y = 4x + 23 and passes through the point (2,3).
kupik [55]

Answer: y=4x-5

Step-by-step explanation:

The slope of y=4x+23 is:4 m=4  

The parallel line needs to have the same slope of 4

Solve it using the "point-slope" equation of a line:   y− y1 = 2(x − x1)

substitute or put in the point (2,3):

y − (3) = 4(x − 2)

y - 3 = 4x - 8      

 put it in slope intercept form y = mx + b  

y  = 4x − 5
