The number would normally be t*10+u. If you swap the digits it becomes u*10+t.

Subtract. (5x2−3x−2)−(−2x2−x+10) Express the answer in standard form. Enter your answer in the box.

Nimfa-mama [501]

Answer:

$7x^{2}-2x-12=0$

Step-by-step explanation:

we know that

The standard form of the quadratic equation is equal to $ax^{2} +bx+c=0$

we have

$(5x^{2}-3x-2)-(-2x^{2}-x+10)$

eliminate the parenthesis

$5x^{2}-3x-2+2x^{2}+x-10$

group terms that contain the same variable

$(5x^{2}+2x^{2})+(-3x+x)+(-2-10)$

combine like terms

$7x^{2}-2x-12=0$

A soma de três númerosemanas é 8470. O primeiro é 4319 e o segundo é 1843. Determine o terceiro número

Mice21 [21]

A soma de 3 numeros igual a 8470 seria:

X + Y + Z = 8470

Como é dito que o 1º é 4319 e o 2º 1843, entao

X + Y + Z = 8470

4319 + 1843 + Z = 8470

Z = 8470 - 4319 - 1843

<h3>Z = 2308</h3>

Simplify 7 - 2(5 - 2x) -10x + 25 -4x - 3

Kisachek [45]

Hi,

Let's simplify this equation step-by-step.

7−2(5−2x)−10x+25−4x−3

Distribute:

=7+(−2)(5)+(−2)(−2x)+−10x+25+−4x+−3

=7+−10+4x+−10x+25+−4x+−3

Combine Like Terms:

=7+−10+4x+−10x+25+−4x+−3

=(4x+−10x+−4x)+(7+−10+25+−3)

=−10x+19

Answer:

=−10x+19

Have a great day!
