Mathematics

Alex_Xolod [135]2 years ago
8 0

Solution:

<u>Note that:</u>

  • 2(Perimeter of smaller triangle) = Perimeter of larger triangle

<u>Using the perimeter of the smaller triangle, solve for x.</u>

  • 2(Perimeter of smaller triangle) = Perimeter of larger triangle
  • => 2(3.5 + x + h) = 7 + 4 + 2h
  • => 7 + 2x + 2h = 7 + 4 + 2h
  • => 2x = 4
  • => x = 2

The length of x is 2 units.

Vika [28.1K]

Answer:

1) x²+4x=2700

2) 50x50

Step-by-step explanation:

Pony area = x²

line-up area=4x

x²+4x=2700

x²+4x-2700=0

(x-50)(x+54)

So x= 50 or -54.  Since it can’t be a negative number, it must be 50.

CHECK:

Square = 50x50 = 2500

Line up area = 50x4 = 200

2500+200=2700 YES

Zapisz w jak najprostszej postaci:<br> a) -x-4(1-x)<br> b) 3(5x-2)-5(3-4x)<br> c) √2(3-x)-2(1-x√2)
Sonja [21]

Answer:

Step-by-step explanation:

a) -x-4(1-x)  =

− 2 x −4 ( 1 − x ) .

2 x − 4

b) 3(5x-2)-5(3-4x)  =

3 ⋅ (5 x − 2 ) − 5 ⋅ ( 5 − 4 x )

35 x  −  31

c) √2(3-x)-2(1-x√2) =

√ 2 x ⋅ ( 3 −x ) − 2 ⋅( 1 − x √ 2 ) .

2 x √ 2 + 3 √ 2 x -√ 2 x x − 2
