I dont get the question so im going to show you both solutions
if you’re asking for (2m+5)²=0 then
(2m+5)²=0 /√
2m+5=0
m=-5/2
if you’re asking only for (2m+5)² then
4m²+20m+25
Simplify
Let's simplify step-by-step.
x(5)−3(x−4)
Distribute:
=x(5)+(−3)(x)+(−3)(−4)
=5x+−3x+12
Combine Like Terms:
=5x+−3x+12
=(5x+−3x)+(12)
=2x+12
Answer:
=2x+12
Answer:
m<BCA+m<BCD=180
Step-by-step explanation:
supplementary means that the angle measures add up to 180°, if you are using the definition of supplementary angles AND you have had a statement saying that two angles are supplementary, ALWAYS follow it with the sum of the measures of those angles equal 180 :)
Answer:
144m
Step-by-step explanation:
we would used tan 30 to determine the height of the building
tan 30 = opposite / adjacent
0.5774 x 250 = 144m
Answer:
to find the area of a polygon
formula: area = 1/2 x perimeter x apothem
Step-by-step explanation:
Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.
