Explain why √3x+2 = -16 has no solution.

The equation you wrote has no solutions since the left hand side is equal to 6x-10 and the right hand side is equal to 6x+8. Setting them equal we get -10=8 which is obviously wrong.

Answer:

Step-by-step explanation:

If we subtract 2 from both sides we have √3x= -18

It's impossible to take a square root of a number and have it be negative

Not sure what form you want this in:

Simplified this is 4x+4y

Factorised this is 4(x+y)

Could someone help me please?

Answer:

a. 7.2

b. 6

Step-by-step explanation:

Since the side lengths of similar polygons are proportional to each other, therefore:

$\frac{b}{10} = \frac{9}{15} = \frac{a}{12}$

Thus, let's find b using:

$\frac{b}{10} = \frac{9}{15}$

Cross multiply

$b*15 = 10*9$

$15b = 90$

Divide both sides by 15

b = 6

Let's find a using:

$\frac{9}{15} = \frac{a}{12}$

Cross multiply

9*12 = 15*a

108 = 15a

Divide both sides by 15

a = 7.2
