The triangle will be enlarged by a scale factor of 10. mc018-1.jpg what will be the area of the new triangle? 35 square cm 700 square cm 3,500 square cm 7,000 square cm

The correct option is 3.

Step-by-step explanation:

The area of a triangle is

Where, b is base of the triangle and h is the height of the triangle.

From the given figure it is noticed that the base of the triangle is 10 cm and the height of the triangle is 7 cm.

The triangle enlarged by a scale factor of 10. Now,

The area of new triangle is

Therefore the area of new triangle is 3500 cm². Option 3 is correct.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
