Anvisha [2.4K]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

The given Angles (4x + 2) and (3x + 3) are forming linear pair, so

$4x + 2 + 3x + 3 = 180$

$7x + 5 = 180$

$7x = 180 - 5$

$7x = 175$

$x = \dfrac{175}{7}$

$x = 25$

now, let's find Angle DCB :

$3x + 3$

$(3 \times 25) + 3$

$75 + 3$

$78 \degree$

What is the value of 9x^2 + 13x – 15, if x = 2

Paladinen [302]

Step-by-step explanation:

Given,

$9 {x}^{2} + 13x - 15$

and

$x = 2$

Substitute x = 2 into expression.

$9 {x}^{2} + 13x - 15 = 9( {2}^{2} ) + 13(2) - 15 \\ = 9(4) + 26 - 15 \\ = 36 + 26 - 15 \\ = 62 - 15 \\ = 47$
