Answer:

see below

Step-by-step explanation:

Assuming s and t are parallel

The two angles are same side interior angles and same side interior angles add to 180 when the lines are parallel

4x-12 + 120 = 180

4x -12 = 60

4x = 72

x = 18

That means 4x -12 = 4(18) -12 = 60

Vertical angles are equal.    Alternate interior angles are equal.  Alternate exterior angles are equal.  All pink dot angles are equal.

Pink dots are 60 degrees

All blue lines are equal.  They are 120 degrees

Find gf(2) if f(x)=2x+1,g(x)=3x-2
natali 33 [55]

Answer:

Step-by-step explanation:

To find g f(2) , evaluate f(2) and substitute the value obtained into g(x)

f(2) = 2(2) + 1 = 4 + 1 = 5 , then

g(5) = 3(5) - 2 = 15 - 2 = 13

find an expression for the area of a rectangle of sides 2x+3 and x-1 given that the perimeter is 28cm what is the value of x
Ierofanga [76]

Answer:

4cm

Step-by-step explanation:

Given data

L=(2x+3)

W=(x-1)

P=28cm

A= L*W

A= (2x+3)*(x-1)

open bracket

A= 2x^2-2x+3x-3

collect like terms

A= 2x^2+x-3

P= 2L+2W

P= 2*(2x+3)+2(x-1)

P= 4x+6+2x-2

collect like terms

P= 6x-4

but p= 28

28= 6x-4

28-4= 6x

24= 6x

x= 24/6

x= 4cm

Hence x= 4cm
