Which expression is equivalent to 30m2+12m+18?? Please help ASAP !
ANTONII [103]

Answer:

c) 6(5m2+2m+3)

Step-by-step explanation:

Given expression = 30m2 + 12m + 18

The simplified form can be calculated by taking GCF

The GCF of 30m2, 12m and 18 is = 6

Therefore, the expression becomes

(6*5m2 + 6*2m + 6*3)

=> 6(5m2+2m+3) so option c is correct

Find the radius of the circle whose equation is 3x² + 3y² = 75.
Flauer [41]

Answer:

<h2>A) 5</h2>

Step-by-step explanation:

The equation of a circle:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

We have the equation:

3x^2+3y^2=75             <em>divide both sides by 3</em>

x^2+y^2=25\to r^2=25\to r=\sqrt{25}\to r=5
