Answer:

x = 2.4

Step-by-step explanation:

Simplify.

24 - 4x + 4 = 6x + 2 - 6

Combine like terms (24 + 4 = 28, sorry for the confusion!)

28 - 4x = 6x - 4

Add x and add 4 to both sides.

10x = 32

x = 3.2

I get see photo. I l ow this is wrong. Can you help?

mylen [45]

Given the equation:

$y=x^2+x-4$

We will find the value of (y) when ( x = 2i )

Note: i² = -1

so, when x = 2i

$y=(2i)^2+(2i)-4$

Simplifying the answer

So,

$\begin{gathered} y=4i^2+2i-4 \\ y=4\cdot(-1)+2i-4 \\ y=-4+2i-4 \\ y=-8+2i \end{gathered}$

So, the answer will be y = -8+2i

AUVW - APOR

Bezzdna [24]

Answer:

x = 54

Step-by-step explanation:

Since both triangles are similar, therefore,

$\frac{UV}{PQ} = \frac{VW}{QR}$

$\frac{77}{66} = \frac{63}{x}$

$\frac{7}{6} = \frac{63}{x}$

Cross multiply

$7*x = 63*6$

$7x = 378$

Divide both sides by 7

x = 54
