The length of two sides of triangle are 4cm and 5cm. Between what two

Elanso [62]

Answer:

1 and 9

Step-by-step explanation:

By the Triangle Inequality Theorem, the sum of two side lengths of a triangle is always greater than the length of the third side.

In other words, in a triangle with side lengths $a, b,$ and $c,$ we always have $a+b > c.$

Applying this to this question, the other side length, $x,$ must satisfy the following inequalities:

$4+5 > x,\\x+5 > 4,\\x+4 > 5.$

Solving these inequalities gives

$x < 9,\\x > -1,\\x > 1.$

Combining these solutions, we have $1 < x < 9.$ Therefore, the length of the third side falls between 1 and 9.

Answer:

2x(5x + 14) + 15

Step-by-step explanation:

Given: (2 $x^{2}$ + 3)(4x + 5) - 8x( $x^{2}$ - 2)

(2 $x^{2}$ + 3)(4x + 5) - 8x( $x^{2}$ - 2) = 2 $x^{2}$ (4x + 5) + 3(4x + 5) - 8x( $x^{2}$ - 2)

= (8 $x^{3}$ + 10 $x^{2}$ + 12x + 15) - 8 $x^{3}$ + 16x

= 8 $x^{3}$ + 10 $x^{2}$ + 12x + 15 - 8 $x^{3}$ + 16x

collecting like terms to have,

8 $x^{3}$ - 8 $x^{3}$ + 10 $x^{2}$ + 12x + 16x + 15

10 $x^{2}$ + 28x + 15

Thus,

(2 $x^{2}$ + 3)(4x + 5) - 8x( $x^{2}$ - 2) = 10 $x^{2}$ + 28x + 15

= 2x(5x + 14) + 15
