Atriangle has an area of 30cm2. the base and height are scaled by a factor of 4.
what is the area of the resulting triangle ?

can you tell me how you got the answer too because i’m trying to figure this out lol

The area of the resulting triangle is

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z-----> the scale factor

x-----> the area of the resulting triangle

y-----> the area of the original triangle

so

we have

substitute and solve for x

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
