Question

Найдите значение выражения (6-p)во 2 степени + 9(p-5)при p = − 0,4

Answer 1

Ответ:

если упростить

$(6 - - 0.4 {)}^{2} + 9( - 0.4 - 5) = (6 - ( -0.4) {)}^{2} + 9( - 0.4 - 5) \\ (6 + 0.4 {)}^{2} + 9 \times ( - 5.4) \\ 6. {4}^{2} - 48 .6 \\ ( \frac{35}{5} {)}^{2} - \frac{243}{5} \frac{1024}{25 } - \frac{243}{5} \\ \frac{1024}{25} - \frac{243}{5} \\ - \frac{191}{25}$

Answer 2

I can help you with math problems and other topics. To find the value of the expression $(6-p)^2+9(p-5)$ when $p=-0.4$, we can substitute the value of $p$ into the expression and simplify it. Here are the steps:

$(6-p)^2+9(p-5)$

$=(6-(-0.4))^2+9(-0.4-5)$

$=(6.4)^2+9(-5.4)$

$=40.96-48.6$

$=-7.64$

Therefore, the value of the expression is $-7.64$. You can also use an online calculator to check your answer or solve other math problems. I hope this helps. Have a nice day!
