Answer:
1.we know the perimeter of the triangle=x-3+x+6+x=3x+3
so,answer is (b)3x+3
2.area of the triangle=1/2*b*h
=1/2*x+2*2x+6=x+2*2x+6/2=2x^2+6x+4x+12/2=2x^2+10x+12/2=2(x^2+5x+6)/2=x^2+5x+6
so,answer is(b)x^2+5x+6
A squared plus B squared equals C squared, so what you need to do it square 5 and 7.
5 = 25
7 = 48
Then add then and square root your answer. 48 + 25 = 73. 73 square rooted equals an rounded amount of 8.6. SO the answer is D

Step-by-step explanation:
Answer:
-7/2isa answer or -3 1/2
Step-by-step explanation:
y=-7x/2-1
y+7/2 x+1=0
slope=-(7/2)/1=-7/2
side length of square = 8
perimeter of square = 4*(side length) = 4*8 = 32
perimeter of square = perimeter of circle = circumference = 32 cm
circumference formula is
C = 2pi*r
32 = 2pi*r .... plug in the given circumference
32/(2pi) = (2pi*r)/(2pi) .... divide both sides by 2pi
16/pi = r
r = 16/pi
r = 16/pi = the exact radius in terms of pi
r = 5.092958 = the approximate value of the radius
The units for the radius are in centimeters.
