ANSWER:

We have to find new side-lengths of PQR triangle.

Original sides are.

$\begin{gathered} PQ\text{ = 8cm} \\ QR=17\operatorname{cm} \\ RP=15\operatorname{cm} \end{gathered}$

After multiplying by 2.5 we get

$\begin{gathered} PQ^{\prime}=2.5\times PQ=(8\times2.5)cm=20\operatorname{cm} \\ QR^{\prime}=(17\times2.5)cm=42.5\operatorname{cm} \\ RP^{\prime}=(15\times2.5)cm=37.5\operatorname{cm} \end{gathered}$

These are the new sides of the P'Q'R' triangle.

Given f(x) = 6x^4 – 10x^3 + 40x – 50, find f(2)

ASHA 777 [7]

F(x)=6x^4-10x^3+40x-50, plug 2 in for x
f(2)=6(2)^4-10(3)^3+40(2)-50
f(2)=12^4-30^3+80-50
f(2)=20735-27,000+80-50
f(2)=-6,235

9- 4(2p+3) - 8p+7<br> how do i solve this ?

Sholpan [36]

Answer:

$= -16p+4$

Step-by-step explanation:

First we simplify:

$9-4(2p+3)-8p+7$

Then we distribute:

$=9+(-4)(2p)+(-4)(3)+(-8p)+7\\=9+(-8p)+(-12)+(-8p)+7$

Lastly, combine like terms:

$=9+-8p+-12+-8p+7\\=(-8p+-8p)+(9+-12+7)\\=-16p+4$

Hope this helps!

Have a good evening! :)
