Answer:

The product is x² + 5x + 6 which is same with the product of (x + 3)(x + 2)

Step-by-step explanation:

Using the smaller square or rectangle to find the product of (x + 3)(x + 2) , we find the area of each rectangle or square. The area means multiplying the length of each square or rectangle to it width.

The first row can be multiplied with each column as follow

x² + x + x + x = x² + 3x

second row with each column

x + 1 + 1 + 1 = x +3

third row with each column

x + 1 + 1 + 1 = x + 3

adding the whole results

x² + 3x + x + 3 + x + 3 = x² + 5x + 6 which is the same as the product of (x + 3)(x + 2)

The answer is c because every quadrilateral adds up to 360 so when you add all the numbers you get 290 and when you subtract 360-290 is 70.

3 lines are shown. A line with points C, A, F intersects a line with points E, A, B at point A. A line extends from point A to p

Verizon [17]

Answer:

m < EAD = 29 degrees

m < CAB = 119 degrees

Given :

The question states that m < CAE = m<FAB = 61 degrees and m<DAF = 90 degrees

Solution:

1. Since line CAF and EAB intersect each other, m<CAF = m< EAF - (opposite vertical angles are equivalent)

2. m<BAC + m<EAC = 180 degrees (sum of linear pair)

3. m<CAB = 180 degrees - m<EAC

4. Equation 1: m<CAB = m<EAF = 119 degrees

5. m<EAF = m<EAD + m< DAF

6. m<EAD = m<EAF - m<DAF

7. m<EAD = 119 degrees-90 degrees = 29 degrees

Hope this helps!!! :)

Find the y-intercept for the parabola defined by the equation y=x^2-x-12

o-na [289]

Answer:

The y-intercept is (0,-12).

Step-by-step explanation:

Given equation is $y=x^2-x-12$ .

Now question says to find the y-intercept of the given parabola $y=x^2-x-12$ .

We know that y-intercept means the y-value when x-value equals 0

so let's plug x=0 into given equation $y=x^2-x-12$ then solve that for y.

$y=x^2-x-12$

$y=0^2-0-12$

$y=0-0-12$

$y=-12$

Hence the y-intercept is (0,-12).
