Answer:

39 units²

Step-by-step explanation:

A line segment from R to V will divide the figure into a 5 by 6 rectangle and a triangle with base 6 and height 3. Appropriate area formulas will help you find the areas of these parts. The total area is the area of the parts.

rectangle area = L·W = 5·6 = 30 . . . units²

triangle area = 1/2·b·h = 1/2·6·3 = 9 . . . units²

Then the polygon area is ...

polygon area = rectangle area + triangle area = (30 +9) units² = 39 units²

Answer:

22

Explanation:

The problem said that Gabriella spent half her weekly allowance buying pizza.
So we know that whatever her weekly allowance is it has to be cut in half.
If she ended up with $14 then we can double that number and take away 6.

I’m not 100% sure that this is the right answer but I hope it helped!

What is the product of (2x-7) and (3x + 3)?

<h3>✒️EVALUATION </h3>

==================================

$\large\sf\underline{Problem:}$

What is the product of (2x-7) and (3x + 3)?

A. 6x2 + 15x-21
B. 6x2 - 15x - 21
C. 6x2 + 15x + 21
D. 6x2 - 15x + 21

==================================

$\large\sf\underline{Answer:}$

$\qquad \qquad \huge \rm Letter\:B.$

*Please read and understand my solution. Don't just rely on my direct answer*

==================================

$\large\sf\underline{Solution:}$

Here we have the given choices:

A. 6x2 + 15x-21
B. 6x2 - 15x - 21
C. 6x2 + 15x + 21
D. 6x2 - 15x + 21

Solve this equation using the distributive property,where you multiply each term to get the number.

$\begin{gathered} \rm2x - 7 = \boxed{ 6} \: \bigg| \small\boxed{\: 6 {x}^{2} } \\ \rm (7)(3) = \boxed{21} \bigg | \boxed{\: 21 x} \\ \\ \qquad \rm6x^{2}+(6x- 21x)-21 \\ \qquad \boxed{ \rm6 {x}^{2} + 15x - 21}\end{gathered}$

Therefore, the correct option is letter B.

Answer:

(2, -1)

Step-by-step explanation:

We can add the first equation by the second

(4x + 6y = 2)+(-4x + 4y = -12)=

10y=-10

we divide both sides by 10 to get

y=-1

We plug -1 in the second equation to get:

-4x+4(-1)=-12

-4x-4=-12

-4x=-8

Now, we divide both sides by -4

x=2

Hope this helps!
