Answer:63/2

Step-by-step explanation:

Just a rectangle + a triangle.

Area of the rectangle is 3*7=21

Area of triangle is 7 * 3/2 = 21/2.

Hence, our total area is 21 + 21/2, or 63/2.

What is the equation of a line that is parallel to 4x+6y+5=0 and passes through the points (6,9)

OLga [1]

Step-by-step explanation:

Equation of given line is:

$4x+6y+5=0 \\ \therefore \: 6y = - 4x - 5 \\ \\ \therefore \: y = \frac{ - 4x - 5}{6} \\ \\ \therefore \: y = \frac{ - 4x}{6} - \frac{5}{6} \\ \\ \therefore \: y = - \frac{ 2}{3}x - \frac{5}{6}...(1) \\ equating \: eq \: (1) \: with \: y = mx + c, \:we \:\\ find : \\ slope \: of \: given \: line \: (m) = - \frac{ 2}{3} \\ \because \: required \: line \: is \: \parallel \: to \: given \: line \\ \therefore \: slope \: of \: required \: line \\ = slope \: of \: given \: line \: (m) = - \frac{ 2}{3} \\ \because \: required \: line \: passes \: through \: \\ point \: (6, \: 9) \\ \therefore \: \: equation \: of \: line \: in \: slope \: point \: \\ form \: is \: given \: as: \\ y-y_1=m(x-x_1) \\ \therefore \:y - 9 = - \frac{ 2}{3}(x - 6) \\ \therefore \:3(y - 9 )= - 2(x - 6) \\ \therefore \:3y - 27= - 2x + 12 \\ \therefore \:2x + 3y - 27 - 12 = 0 \\ \purple{ \boxed{\therefore \:2x + 3y - 39 = 0}} \\ is \: the \: equation \: of \: required \: line$

Choose Yes or No to tell if each pair of expressions is equivalent. 3x + 14 – x + 112 and 4x + 134 Choose... 2 + 6x and 2(3x + 1

natima [27]

Answer:

B. 2 + 6x and 2(3x + 1) Choose

D. 3x and 4(x + 1) – x – 4 Choose...

E. 5.5 + 2.1x + 3.8x – 4.1 and 1.4 + 5.9x Choose...

Step-by-step explanation:

A. 3x + 14 – x + 112 and 4x + 134 Choose...

3x + 14 - x + 112

= 2x + 126

And

4x + 134

Not equivalent

B. 2 + 6x and 2(3x + 1) Choose...

2 + 6x

And

2(3x + 1)

= 6x + 2

Yes, equivalent

C. 3(x + 1) – (1 + x) and 2x + 3 Choose...

3(x + 1) - (1 + x)

3x + 3 - 1 - x

2x + 2

And

2x + 3

No, not equivalent

D. 3x and 4(x + 1) – x – 4 Choose...

And

4(x + 1) - x - 4

= 4x + 4 - x - 4

= 3x

Yes, equivalent

E. 5.5 + 2.1x + 3.8x – 4.1 and 1.4 + 5.9x Choose...

5.5 + 2.1x + 3.8x - 4.1

1.4 + 5.9x

And

1.4 + 5.9x

Yes, equivalent
