The answer will be B because the triangles are congruent so 5x-10.6 = 38.4 add 10.6 on both sides u get 5x = 49 now divide 5 on both sides u get x = 9.8. hope u get this correct!

One number is nine more than another number. If the sum of the numbers is 65 find both numbers

velikii [3]

Answer:

THEY ARE 37 AND 28

Step-by-step explanation:

LET THE NUMBERS BE X AND Y

X = 9 + Y

X - Y = 9 ........1

X + Y = 65 .....2

ADDING 1 AND 2

2X = 74

DIVIDING BY 2

2X/2 = 74/2

X = 37

AND X = 9 + Y

: Y = X - 9

PUTTING X = 37

Y = 37 - 9

Y = 28

BRAINLIEST!! HELP.. <br> 4. Simplify the given expression.

QveST [7]

Answer:

$\frac{( {x} + 1) (x - 1)(16 {x} - 37)}{( {x}^{2} + 2)}$

Step-by-step explanation:

$\frac{ \frac{3 {x}^{2} - 3 }{x} }{ \frac{3( {x}^{2} + 2)}{16 {x}^{2} - 37x } \\ \\ = \frac{3( {x}^{2} - 1) }{x} \times \frac{x(16 {x} } - 37)}{3( {x}^{2} + 2)} \\ \\ = \frac{3( {x} + 1) (x - 1)}{x} \times \frac{x(16 {x} - 37)}{3( {x}^{2} + 2)} \\ \\ = \frac{( {x} + 1) (x - 1)}{1} \times \frac{(16 {x} - 37)}{( {x}^{2} + 2)} \\ \\ = \frac{( {x} + 1) (x - 1)(16 {x} - 37)}{( {x}^{2} + 2)}$
