Solve using long division.

Mkey [24]

Answer:

Quotient is $3x-5$ and remainder is 0.

Step-by-step explanation:

Given:

Dividend = $3x^2+7x-20$

Divisor = $x+4$

The long division is shown in the attachment.

Step 1: we need to divide $3x^2+7x-20$ with $x+4$ we first multiply $x+4$ with 3x we get the remainder as $-5x-20$

Quotient as 3x.

Step 2: Now the dividend is $-5x-20$ and divisor $x+4$ now we will multiply $x+4$ with -5 we get the remainder as 0 and Quotient as $3x-5$

Hence Quotient is $3x-5$ and remainder is 0.

Please help I’ll mark brainliest if correct please explain also

adell [148]

Answer:

2/5

Step-by-step explanation:

5x+6y=11

as we have to find x coordinate

while y coordinate 3/2 is already given in question

so only put value of y coordinate in given equation to get x coordinate value

5x+6y=11

5x+6*(3/2)=11

5x+3*3=11

5x+9=11

5x=11-9

5x=2

x=2/5

the length of a rectangle is 3 units shorter than one -third of the width, x. Which expression represents the perimeter of the r

Mariana [72]

Answer:

A) $\frac{8}{3} x - 6$

Step-by-step explanation:

Let the width of the rectangle be x units.

$\therefore \: length \: of \: rectangle = \frac{1}{3} x - 3 \\ Perimeter \: of \: rectangle = 2(l + w) \\ = 2 \bigg( \frac{1}{3} x - 3 + x \bigg)\\ = 2 \bigg( x + \frac{1}{3} x - 3 \bigg)\\ = 2 \bigg( \frac{3x + x}{3} - 3 \bigg)\\ = 2 \bigg( \frac{4x}{3} - 3 \bigg) \\ = 2 \bigg( \frac{4x}{3} - 3 \bigg) \\ = \frac{2 \times 4x}{3} -2 \times 3 \\ \purple{ \bold{{Perimeter \: of \: rectangle = \frac{8}{3} x - 6}}}$

X^lg(x)=100^x find x

Wittaler [7]

$x^lg(x)=100^x$

$X^lg(x)=100^x:x$ $|Solve \ for \ x|$

$|Use \ logarithms \ of \ both \ sides \ of \ the \ base \ 10|

$

$lg (x ^ lg (x)) = lg (100x)

$

$lg ^ 2 (x) = 2 + lgx$

$lg 2 ^ x-lg x -2 = 0$

$lg x = 2 x = 100$

$lg x = -1 x = \dfrac{1}{10} = 0.1$

Please help me with this thanks so much to whoever is helping me

netineya [11]

Answer:

X = 80

Step-by-step explanation:

A flat line is equal to 180 degrees, meaning that if you use linear, you can find out that if you subtract 100 from it, it becomes 80, which resembles the X.
