Answer:The lateral area is $364\ cm^{2}$

Step-by-step explanation:

we know that

The lateral area of the right prism is equal to

$LA=Ph$

where

P is the perimeter of the base

H is the height of the prism

Find the perimeter of the base P

$P=4(7)=28\ cm$ ----> the rhombus has four equal sides

$h=13\ cm$

substitute

$LA=28(13)=364\ cm^{2}$

Answer:

Triangle ABC is similar but not congruent to Triangle XYZ

Step-by-step explanation:

When you dilate the size changes but the angles are the same with makes them similar and since the size of the triangles are different they cannot be congruent.

Link is coloring a triforce, which consists of four equilateral triangles and is depicted below. He has three colors to use: gol

3241004551 [841]

Answer:

12

Step-by-step explanation:

For the top triangle, he has 3 options

3C1 = 3

For the middle one, he can't use the top triangle's colour, so 2 options

2C1 = 2

For the ones on sides of the middle one, 2 options each

2C1 × 2C1 = 4

3 × 2 × 2 × 2 = 24

These include all three outer ones same, so subtract 3

Also, these include 2 of the three outer ones same, so subtract:

3C2 × 3 = 9

24 - 3 - 9 = 12

1.)Painting Jane is painting one wall of her living room. The wall is rectangular, 13 feet wide by 9 feet high. What is the area

antiseptic1488 [7]

Answer:

1. $117 ft^{2}$

2. $54 ft^{2}$

3. $1,428 ft^{2}$

4. $644 ft^{2}$

5. $4,700 ft^{2}$

6. $57,600 ft^{2}$

Step-by-step explanation:

First use $A = w*l$

$w = width$

$l = length$

It doesn't have to be $A = w*l$ , it could be $A = l*w$ . It will be the same answer.

1. $3 ft * 9 ft = 117 ft^{2}$

2. $3 ft * 18 ft = 54 ft^{2}$

3. $42 ft * 34 ft = 1,428 ft^{2}$

4. $23 ft * 28 ft = 644 ft^{2}$

5. $94 ft * 50 ft = 4,700 ft^{2}$

6. $360 ft*160 ft = 57,600 ft^{2}$

Which are the solutions of x² = 19x + 12

Sever21 [200]

Answer:

$\{x=\frac{19-\sqrt{409} }{2}\ , \ x=\frac{19+\sqrt{409} }{2}\}$

Step-by-step explanation:

x² = 19x + 12

⇔ x² - 19x - 12 = 0

Calculating the discriminant :

b² - 4ac = (-19)² - 4×1×(-12) = 409

The discriminant is positive ,then the equation has two solutions.

$x=\frac{19-\sqrt{409} }{2} \ \ or\ \ x=\frac{19+\sqrt{409} }{2}$
