Answer:

x = 5

Step-by-step explanation:

The small triangle has been dilated by 2 making it twice as big as before.

The side that measures 10 would be dilated by 0.5 to find x which is half a big.

10 x 0.5 = 5

Now check your work. On one side it asks 6x. So, 6 x 5 = 30. Since 30 is twice as much as 15. The rule applies that x = 5.

5 x 2 = 10

6 x 5 = 30

15 x 2 = 30

Solve the equation without the use of a calculator. please Help!!! Thank you!!!<br> 12x^3-30x=5-2x^2
nata0808 [166]

So, since we have a cubic equation with 4 terms, the first thing we should try is factoring by grouping, so:

12x^3+2x^2-30x+5 =0 \implies \\ 2x^2(6x+1)-5(6x+1)=0 \implies \\ (2x^2-5)(6x+1) = 0

Now that we've factored our equation, we can use ZPP and break it up:

2x^2-5 = 0 \implies \\ 2x^2=5 \implies\\ x^2=\frac{5}{2} \implies\\ x=\pm\frac{\sqrt{5}}{\sqrt{2}}=\pm\frac{\sqrt{10}}{2} \\ \\ 6x+1 =0 \implies \\ 6x=-1 \implies\\ x=\frac{-1}{6}

So, our solutions are:

x\in \{\frac{\sqrt{10}}{2},-\frac{\sqrt{10}}{2},-\frac{1}{6}\}

Answer:

5y + 4 and 7y + 4 - 2y

Step-by-step explanation:

Look at  the second choice:-

5y + 4  and 7y + 4 - 2y

Simplifying the second expression:-

7y + 4 - 2y

= 5y + 4

So both expressions are equivalent . Therefore if you plug in 2 or 5 the results will be the same.
