Since the triangle is isosceles, then (x + 4) must be equal (3x - 8)

Solving the (x + 4) = (3x - 8), we'll get:

(x + 4) = (3x - 8)

3x - x = 8 + 4

2x = 12

x = 6

So, the length of AC is 6 units

Step-by-step explanation:

AC=AB+BC

AC=x+4+3x‐8

COMBINE LIKE TERMS

AC=x+3x

AC =4x+4‐8

=4x+‐4

=0

A rectangle has a perimeter of 60 units and one side of length 18 units. If it can be determined, what are the lengths, in units
ladessa [460]

Answer:

option B. 18,12,12

Step-by-step explanation:

perimeter= 60 units

(consider a rectangle with sides a,b,c & d in order)

a= 18 units (given)

c=18 units (since opp. sides of a rectangle are equal)

now the remaining length= 60-(18+18)

                                          = 60 - 36

                                          = 24

so the sum of the remaining sides, ie, b+d= 24

since b and d are equal (opp.sides of a rect.)

b=d=24/2=12

therefore, b=12; c=18; d=12

i really hope i'm clear...but if i'm not then please do ask...

Using the equation of the line (y = 0.5x + 79), what would be the melting point of dna with 50% gc content? enter your answer as
steposvetlana [31]
We have the equation of the line as follows:
y = 0.5x + 79

We want to calculate the melting point (the y value) of DNA  with 50% gc content (the x value).
The gc content represents the value of x in the equation, so to calculate the melting point (y), we will simply substitute the x with 50 in the equation of the line as follows:
melting point = 0.5(50) + 79 = 25 + 79 = 104 degrees
