4 square units.
The easiest way to find this is by looking at the triangle as if NL was the base. In this case PM would be the height. Since a triangle is the same shape even when we move it or rotate it, this is a common strategy to finding areas when the direction is tough for us.
Now that we have this we can measure the lengths of the base and height and use them in the triangle area formula.
Base = 4
Height = 2
Area of a triangle = 1/2bh
Area of a triangle = 1/2(4)(2)
Area of a triangle = 2(2)
Area of a triangle = 4
A=LW
L=W-4
A=252
sub W-4 for L
A=(W-4)(W)
252=(W-4)(W)
252=W²-4W
minus 252 both sides
0=W²-4W-252
what 2 numbers multiply to get -252 and add to get -4
-18 and 14
0=(W-18)(W+14)
set to zero
W-18=0
W=18
W+14=0
W=-14
false, we can't have negative width
Width=18
L=W-4
L=18-4
L=14
length=14cm
width=18cm
Answer:
a<5
Step-by-step explanation:
a/5<1
5*a/5<1*5
a<5
Answer:
<em>Sherita would need to make 10 free throws</em>
Step-by-step explanation:
<u>Proportions</u>
Sherita made 46 of her first 60 free throws in this basketball season. Calculating the average we get:
Sherita wants to have a free throw average of at least 80% in her next x free throws. This means she will have 46+x made throws out of 60+x total throws. For this new performance, the new average would be:
And we equate it to 80% (0.8 in decimal):
Multiplying by 60+x:
Operating:
Subtracting 46 and 0.8x:
0.2x=2
Dividing by 0.2
x = 10
Sherita would need to make 10 free throws
