Lyrx [107]

Answer:

16\frac{2}{3}cm

Step-by-step explanation:

Given dimensions:

           3\frac{1}{6} cm by 4\frac{2}{3}cm  by 5\frac{2}{3} cm

The total length:

 it is the sum of all the sides;

         \frac{19}{6}  + \frac{14}{3}   + \frac{17}{3}  

LCM of the denominators = 6 ;

   \frac{38 + 28 + 34}{6}  = \frac{100}{6}

a – 3b = 22 a = b – 2 What is the solution to the set of equations in the form (a, b)? (–10, –8) (–12, –10) (–8, –6) (–14, –12)
Vinil7 [7]
A = b - 2

a - 3b = 22
(b - 2) - 3b = 22
b - 2 - 3b = 22
-2 - 2b = 22
-2b = 24
-b = 12
b = -12

a = b - 2
a = -12 - 2
a = -14

Solution set {-14, -12}

How to solve question 10
Over [174]

Answer:

Option E x=x^2-10x+21

Step-by-step explanation:

we have

x-5=\sqrt{x+4}

we know that

For x> 5 both sides of the equation will be positive

Squared both sides

(x-5)^2=(\sqrt{x+4})^2

(x-5)^2=(x+4)

x^2-10x+25=(x+4)

Subtract 4 both sides

x^2-10x+25-4=(x+4)-4

x^2-10x+21=x

Rewrite

x=x^2-10x+21
