The rectangle below is enlarged using a scale factor of 1.5. What will be the new length and width of the rectangle?

Likurg_2 [28]

Answer: length = 4.5 m, width = 3 m

Step-by-step explanation:

When a shape is enlarged using a scale factor, you simply multiply each of the sides by the scale factor.

length = 3 * 1.5 = 4.5 m

width = 2 * 1.5 = 3 m

Which set of side lengths can be used to form a right triangle

leva [86]

Answer:

14, 48, 50

Step-by-step explanation:

To check which set of side length can be used to form a right triangle we use pythagorean theorem

c^2 = a^2 + b^2

biggest side (hypotenuse is c^2)

(a) 14, 48, 50

$50^2 = 14^2 + 48^2$

2500= 196+2304

2500= 2500 that is true

(b) 30, 40, 60

$60^2 = 30^2 + 40^2$

3600= 900+ 1600

3600= 2500 that is false

$60^2 = 14^2 + 50^2$

3600= 196+2500

2500= 2196 that is false

(d) 10, 24,28

$28^2 = 10^2 + 24^2$

784=100+576

784=676 that is false

in a certain store, the regular price of a refrigerator is $600. how much money is saved by buying the refrigerator at 20% off t

Advocard [28]

60$. These are my equations :
600 * 0.2 = 120 ; 600 - 120 = 480
Then...
600 * 0.1 = 60 ; 600 - 60 = 540
Which then became....
540 - 480 = 60

How do i Solve: 3x2−6x−12=0 ?

MrMuchimi

Answer:

1 + root 5, 1 - root 5

Step-by-step explanation:

I assume you mean 3x^2-6x-12=0.

First, note that you can divide both sides by 3. You get:

x^2-2x-4=0

Use the quadratic equation.

$x=\frac{2\pm\sqrt{4+16}}{2}=\frac{2\pm2\sqrt{5}}{2}=1\pm\sqrt{5}$

Therefore, x=1 + root 5, 1 - root 5
