Answer:

b^2√30b

Step-by-step explanation:

√30b^5 - Original

Break down the radical with its factors (factor tree)

√3*2*5*b*b*b*b*b

See what perfect squares you can take out (Can take out four b terms) You cant take out any perfect squares involving 30 since there are no perfect squares

b^2√3*2*5*b

b^2√30b

I really need help with this section

Tpy6a [65]

Looks like you did most of it.

The next step would be setting them equal to 105, like the problem suggests.

$5z+3x+7x=105$

$15x=105$

$x=7$

Then we can plug back in to find the numbers.

$5*7=35$

$3*7=21$

$7*7=49$

$35+21+49=105$

The three numbers are $35, 21, 49$ .

Hope this helps.

頑張って!

Find x. <br> Side splitter theorem

professor190 [17]

Answer:

x = 9

Step-by-step explanation:

The outer and inner triangles are similar, thus the ratios of corresponding sides are equal, that is

$\frac{8}{8+4}$ = $\frac{x-3}{x}$ , that is

$\frac{8}{12}$ = $\frac{x-3}{x}$ ( cross- multiply )

12(x - 3) = 8x

12x - 36 = 8x ( subtract 8x from both sides )

4x - 36 = 0 ( add 36 to both sides )

4x = 36 ( divide both sides by 4 )

x = 9
