Answer:

= 1700 :)

Step-by-step explanation:

-multiply all the sides,

-add them,

- then double the answer (or times it by 2):

1) 30 times 20 = 600

30 times 5= 150

20 times 5 =100

2) Add them:

600+150+100 = 850

then times 850 by 2

850 times 2 = 1700

Hope that helped :)

Answer:

(a) 6x + (x + 12) = 180

(b) m<1 = 144 m<2 = 36

Step-by-step explanation:

7x + 12 = 180

7x = 168

x = 24

6(24) = 144

(24) + 12 = 36

On a coordinate plane, how are the locations of the points (-4 , -3) and (4 , -3) related?

Helga [31]

Answer:Dilation involves changing the size of a shape.

The true statement is that the locations of E' and F' are E' (−12, 0) and F' (0, 6), and lines g and g' are parallel.

The given parameters are:

--- the scale factor

Multiply the coordinates of point E and F by the scale factor (k), to determine the new coordinates of E and F.

Given that line g is represented by points E and F; line g' would be represented by points E' and F'

So, both lines would be parallel.

Hence, the true option is (d)

For each graph below, state wether it represents a function.

Paul [167]

Answers:

Row 1: No, No, No

Row 2: Yes, Yes, Yes

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

Explanation:

Use the vertical line test. If it is at all possible to draw a single vertical line through more than one point on the relation curve, then the relation is not a function. This is because a function is only possible when any x input leads to exactly one y output.

So that's why graphs 1,2,3 are not functions, while graphs 4,5,6 are functions.

The volume of a single layer in a rectangular prism is 18 cubic centimeters. There are 5 layers in this rectangular prism. What

sweet [91]

Answer: $90cm^3$

Step-by-step explanation:

A rectangular prism is a three-dimensional solid.

A rectangular prism has six faces (each one of these faces are rectangles), eight vertices and twelve edges.

You know that this rectangular prism has 5 layers and the volume of one of these layers is 18 cubic centimeters ( $18cm^3$ ).

Assuming that all these layers are equal, the volume of this rectangular prism can be calculated with:

$V_{prism}=5*V_1$

Where $V_1$ is the volume of one layer.

Substituting, you get:

$V_{prism}=(5)(18cm^3)\\\\V_{prism}=90cm^3$

Solve. x^2+9x+2=0 thanks!

shtirl [24]

Step one:
ALWAYS set equation equal to zero, which in this case has already been done for us.

Step two:
Figure out what formula you need to use in order to solve in this case I'd use the Quadratic formula.

a=1
b=9
c=2

Quadratic formula:
$x = \frac{ - b + - \sqrt{(b) ^{2} - 4(a)(c)} }{2(a)}$
Then you would plug in the information.
$x = \frac{ - 9+ - \sqrt{(9) {}^{2} - 4(1)(2) } }{2(1)}$
The solve for what is underneath the square root ONLY.
$x = \frac{ - 9 + - \sqrt{73} }{2}$
Since you cannot solve this any further, your final two answers are...
$x = \frac{ - 9 + \sqrt{73} }{2}$
$x = \frac{ - 9 - \sqrt{73} }{2}$
