nordsb [41]

Answer:

7 m^2

Step-by-step explanation:

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

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

$s = 6$

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

$a = b = c$

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

$3a = 12$

$a = b = c = 4$

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

$A = \sqrt{6(2)^3$

$A = \sqrt{48}$

$A = 6.92820...$

$A = 7~m^2$

URGENT: DUE TONIGHT OR I GET DETENTION!!!!

suter [353]

Answer:

63 weeks

Step-by-step explanation:

252 - 3x = 378 - 5x

+ 5x +5x

Add 5x to both sides

252 + 2x = 378

-252 - 252

Subtract 252 from both sides

2x = 126

Divide 2 from both sides

x = 63

Check you work by plugging 63 where the x is

252 - 3(63)

252 - 189 = 63

378 - 5(63)

378- 315 = 63
