find the perimeter of a triangle with sides 15 inches, 15 inches, and 21 inches length
To find the perimeter of a triangle we add all the sides of the triangle
The length of the sides of the triangle are given as 15 inches, 15 inches, and 21 inches
Perimeter of a triangle =
15 inches + 15 inches + 21 inches = 51 inches
So 51 inches is the perimeter
Answer:
90 mph
Step-by-step explanation:
if it can go 45 mph, in 2 hrs, it should go 90
45*2=90
The correct answer is C. Let’s break this down with the distributive property.
5(6x+6)
30x+30
5(9-x)
45-5x
Now add and subtract like terms.
30x-5x=25x
30+45=75
Put the remaining numbers together.
25x+75 and there you go.
<span>Here the given equation is :
2-8x= -6
By bring -6 on the Left Hand size and taking 8x on the Right Hand side, the equation become.
2+6= 8X
8= 8X
X=8/8
X=1
Hence value of X is 1.
Hence correct option is A.</span>
