Answer:

Sample Response: Locate two corresponding ordered pairs of the two shapes. Calculate how much the pre-image values were multiplied by to obtain the image values. This is your scale factor. You can calculate this by dividing the coordinates of the mage by the corresponding coordinates of the pre-image.

hope i helped

The shapes are similar, there was a dilation, which is what made the shape either bigger or smaller. I am not very good with instructions, but I will try to answer my best. You could set up a ratio, Bigger shape/smaller shape, or vice versa. Wish I could have helped more, sorry.

Good Luck! Hope I helped:)

PLEASE HELP ASAP!!!!!!!

Answer:

40 cm² = B

178,127514 ≈ LA

218,127514 ≈ SA

Step-by-step explanation:

First and foremost, since we were not given a height, to find the height, take one-third of the area base [area base in this case is ws, since it is a rectangular base]: $\frac{1}{3}(40) = 13 \frac{1}{3}$

This is your height.

Now, to find the lateral area, we use this formula:

$l \sqrt{(\frac{w}{2})^{2} + {h}^{2}} + w \sqrt{( \frac{l}{2})^{2} + {h}^{2}} = L. A.$

Plugging these numbers into this formula will give you an approximate value of 178,127514.

Then you add the lateral area to the base area to get your surface area:

$40 + 178,127514 = 218,127514$

I am joyous to assist you anytime.

Consider the following equations: −x − y = 1

Vlad1618 [11]

Solve for X and y using both equations the point you get will be the point they cross eachother
-x-y=1
y=x+3
-x-(x+3)=1
-x-x-3=1
-2x-3=1
+3 both sides
-2x=4
÷-2 both sides
x=-2
solve for y
y=-2+3
y=1
(-2,1)

Simplify (2√5+3√7)^2

Anna35 [415]

The answer is: 83 + 12√35

(a + b)² = a² + 2ab + b²

In (2√5 + 3√7)², a = 2√5, b = 3√7

Just substitute a and b:
(a + b)² = a² + 2ab + b² = (2√5)² + 2 * 2√5 * 3√7 + (3√7)² =
= 2²√5² + 2 * 2 * 3 * √5 * √7 + 3²√7² =
= 4 * 5 + 12 * √(5*7) + 9 * 7 =
= 20 + 12 *√35 + 63 =
= 83 + 12√35
