Answer:

Step-by-step explanation:

We know the area of a triangle is B*H/2. For Triangle ABC, the area is 75. So the equation formed is:

15*h/2 = 75

15*h = 150

h = 10.

Now we know the height for the bigger triangle is 10. Since the scale factor from 15 --> 3 is 5, the height for triangle EFG is 2 because 10 divided by 5 is 2. Since we now know the height of the triangle is 2 and the base is 3, we can form the equation:

3*2/2 = Area

6/2 = Area

3 = Area

We know the area is 3. The key thing was we didn't divide triangle ABC with 5 because the area would not be the same. We must use the equation and from this we will get the correct area.

Answer:

Step-by-step explanation:

It is 15.

(15×x) /2 =75

×2. ×2

X×15=150

/15. /15

X=10

(3×x) /2 =area of triangle

(3×10) /2

30/2

15= area of triangle

Use Pythagorean Theorem to solve for the
babymother [125]
Pythagorean theorem is all about squaring the numbers. the equation is a^2+b^2=c^2
when you know two sides of the triangle, you fill in those spaces. they hypotenuse is ALWAYS ‘c’

to figure this problem out you put
a as 4
keep b as b since you don’t know what it is
c as 6

4 squared=16
6 squared=36

16+b^2=36
36-16=20
square root of 20 is 4.47

Answer:

From least to greatest: -2, 2/3

Step-by-step explanation:

Set each factor equal to 0 and solve

2x + 4 =0

2x = -4

x = -2

3x - 2 = 0

3x = 2

x = 2/3

If line y bisects AC, AB = 4-5x, and BC =2x+25, AC
jolli1 [7]
4 - 5x = 2x + 25
4 = 7x + 25
-21 = 7x
-3 = x

4 - 5x + 2x + 25 = ac
4 - 5(-3) + 2(-3) + 25 = ac
4 - (-15) + (-6) + 25 = ac
19 + (-6) + 25 = ac
38 = ac
