What is the solution of sqrtx^2+49 = x+5?

Lady_Fox [76]

Answer:

Step-by-step explanation:

√x² + 49 = x + 5

Square both sides

(√x² + 49)² = ( x + 5)²

x² + 49 = x² + 10x + 25

Simplify

10x = 49 - 25

10x = 24

Divide both sides by 10

Hope this helps you

Which equation can be used to calculate the surface area of the rectangular prism net shown below?

Bess [88]

Answer:

$SA=\frac{1}{2}(5)(12)+\frac{1}{2}(5)(12)+(5)(10)+(12)(10)+(13)(10)$

Step-by-step explanation:

we know that

The surface area is equal to the area of all the faces of the triangular prism

$SA=\frac{1}{2}(5)(12)+\frac{1}{2}(5)(12)+(5)(10)+(12)(10)+(13)(10)$

simplify

$SA=(5)(12)+(5)(10)+(12)(10)+(13)(10)$

$SA=360\ cm^{2}$
