Use suitable identities to find the following products (x+4)(x+10)

Anestetic [448]

Answer:

$x^2 + 14x + 40$

Step-by-step explanation:

Here we gonna use the identity -

$(x+a)(x+b) = x^2+(a+b)x + ab$

So using the identity here,

$(x+4)(x+10) \\=> x^2 +(4+10)x+4*10\\=>x^2+14x+40$

Line c has an equation of y = 4x + 9. Line dis parallel to line c and passes through (-4,-4).

natta225 [31]

Answer:

$\large\boxed{\sf y = 5x +16}$

Step-by-step explanation:

Here it is given that a line c has a equation of ,

$\sf\qquad\longrightarrow y = 4x + 9$

And there is another line d which is parallel to line c and passes through the point (-4,-4) . And we need to find out the equation of the line .

Firstly we know that the slope of two parallel lines is same . So on comparing the given line to the slope intercept form of the line which is y = mx + c , we have ;

$\sf\qquad\longrightarrow m = 4$

Therefore the slope of the parallel line will be ,

$\sf\qquad\longrightarrow m_{||}= 4$

On using the point slope form of the line , we have ;

$\sf\qquad\longrightarrow y - y_1 = m(x-x_1)\\$

Substitute the values ,

$\sf\qquad\longrightarrow y - (-4) = 5\{ x -(-4)\}$

Simplify ,

$\sf\qquad\longrightarrow y +4 = 5(x +4)$

Open the brackets ,

$\sf\qquad\longrightarrow y + 4 = 5x + 20$

Subtract 4/on both sides ,

$\sf\qquad\longrightarrow y = 5x +20-4$

Simplify ,

$\sf\qquad\longrightarrow \pink{ y = 5x + 16}$

Hence the equation of the line is y = 5x + 16

Add. 21 3/4 + 6 3/4 Enter your answer as a mixed number in simplest form by filling in the boxes.

avanturin [10]

I think it’s 27 3/4 since you just had the 21 and 6 together and it should be the same fraction

Expand the following by removing the brackets -2 (3x + 4) m ( my -3)

olasank [31]

Answer:

-6x-8

m^2y-3m

Step-by-step explanation:

For the first one we simply need to multiply both figures in the bracket by the outer number.

For the second one we do the same thing but as there is an "m" in the bracket and an "m" outside the bracket, this makes a square "^2" which is essentially a figure multiplied by itself.
