What is the value of g?<br> 3/5g - 1/3 = -10/3
marshall27 [118]
3/5g-(1/3)=(-10/3)
move the 1/3 over
3/5g=(-10/3)+(1/3)   (notice the + sign)
3/5g= (-9/3)
3/5g=(-3)
move the 3/5 over (divide)
g= (-3/(3/5))
g= (-3x5/3)
g= -15/3
g= -5

nordsb [41]

Answer:

7 m^2

Step-by-step explanation:

s = \dfrac{a + b + c}{2}

A = \sqrt{s(s - a)(s - b)(s - c)}

s = 6

\dfrac{a + b + c}{2} = 6

a = b = c

\dfrac{a + a + a}{2} = 6

3a = 12

a = b = c = 4

A = \sqrt{6(6 - 4)(6 - 4)(6 - 4)}

A = \sqrt{6(2)^3

A = \sqrt{48}

A = 6.92820...

A = 7~m^2
