Answer:
Perimeter =20cm
Length =6
Breath = X
P= 2(l+b)
20 =2(6+x)
20=12+2x
20-12=2x
8=2x
x=8/2
x=4

Answer:
0,-14
Step-by-step explanation:
5(x+7)²=245
divide both sides by 5
(x+7)²=49
Taking the square root of both sides
x+7=±7
Either x+7=7
subtract 7 from both sides
x+7-7=7-7
x=0
or
x+7=-7
subtract 7 from both sides
x+7-7=-7-7
x=-14
3/5 in 30 mins, 5*30=150, then she would write 3/150 or 1/50 each minute
Answer:
x=4
Step-by-step explanation:
To solve for x, use inverse operations:
-8x+3 = -29 Subtract 3 from both sides
-8x +3 -3 = -29 -3
-8x = -32 Divide both sides by -8
x = 4
