Answer:

x = ±5

Step-by-step explanation:

4x^2 = 100

Divide each side by 4

4/4x^2 = 100/4

x^2 = 25

Take the square root of each side

sqrt(x^2) = ±sqrt(25)

x = ±5

Answer:

the missing value is 9.33.

Step-by-step explanation:

given,

length (l) = 3x+2

breadth (b) = 4

perimeter(P) = 68 cm

now,

P = 2(l+b)

or, 68 = 2× ( 3x+2+4)

or, 68 = 2× ( 3x+ 6)

or, 68 = 6x+12

or, 68 - 12= 6x

or, 56 = 6x

or, 6x = 56

or, x = 56/6

or, x = 9.33

1/3(12x-24)=16

3/1[1/3(12x-24)=16]

12x-24=48
+24 +24
12x=72

12x/12=72/12
