Let the common ratio be r.
then 
a2*r*r=a4
rearrange,
r^2=a4/a2=112.5/50=2.25
r=sqrt(2.25)=1.5 = common ratio

Answer:

3(x - 12)(x + 2)

Step-by-step explanation:

Given

3x² - 30x - 72 ← factor out 3 from each term

= 3(x² - 10x - 24) ← factor the quadratic

Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (- 10)

The factors are - 12 and + 2 , since

- 12 × 2 = - 24 and - 12 + 2 = - 10 , thus

x² - 10x - 24 = (x - 12)(x + 2) and

3x² - 30x - 72 = 3(x - 12)(x + 2)

5x + 10 &gt; 35<br> How do you work this out?
Alexxx [7]

Answer:

x > 5

Step-by -step explanation:

Solving inequalities is similar to solving equations.

5x + 10 > 35

Subtract 10 from both sides.

5x > 25

Divide by 5 from both sides to isolate the x.

x > 5

Instructions: Problem 1 ! Find the missing angle in the image below. Do not include spaces in your answers
sweet-ann [11.9K]

Answer:

40 degrees

Step-by-step explanation:

The 100 degree angle is supplementary to angle CED. This means CED will end up being 80 degrees. Since the angles in all triangles equate to 180 degrees 80 + 60 + angle D must equal 180 degrees. Therefore, angle D has to be 40 degrees.
