\left \{ {{S=14+L} (I) \atop {S+L=124}(II)} \right.

<span>Substitute (I) into (II), we have:
</span>S+L=124
(14+L)+L=124
14 + 2L = 124
2L = 124 - 14
2L = 110
L =  \frac{110}{2}
\boxed{L = 55}

<span>Replace (II) in (I), we have:
</span>S=14+L
S = 14+ 55
\boxed{S = 69}

FInd the surface area of the triangular prism
Marta_Voda [28]

Answer:

273.7

Step-by-step explanation:

first fine the sides that isn't the base.

triangle area formula: (b*h)/2

(14*9)/2 = 63

since there are 3 sides you multiply this by three.

63*3=189

then find the base.

same formula since its a triangle.

(12.1*14)/2 = 84.7

now add them both up:

84.7+189 = 273.7

hope this helps!

X=|y| what is the domain and range ?
cricket20 [7]

Answer:

Domain: x ≥ 0

Range: All real numbers

Step-by-step explanation:

This is an absolute value function which creates a V for its graph. Since the absolute value is on y, the function is rotated to the right or sideways.

This means only the x values of 0 and greater are used in the function. Since the domain is the set of all x values then it is x≥0.

This also means that all y values are used on the y-axis. There is no restriction on the y values. Since the range is the set of all y values then it is all real numbers.
