Use the numbers 8, 6, and 2 and one operation to write and expression that includes an exponent and has a value of 8. Use each n

Vesnalui [34]

Answer:

$6+2^{1}=8 \Rightarrow 6+2=8 \Rightarrow 8=8$

Step-by-step explanation:

1) One solution is to write, as our exponent:

$2^{1}=2$

2) Because this is special case of the Exponents Law, valid for every base ≠ 0.

$a^{1}=a$

3) Hence, including an exponent the numbers 6, 2 whose value is eight.

$6+2^{1}=8 \Rightarrow 6+2=8 \Rightarrow 8=8$

Therefore our expression is true

The length of a rectangle is 5 cm less than 3 times its width. If the perimeter is 70 cm, find the dimensions.

zvonat [6]

Answer:

l = 25

w = 10

Step-by-step explanation:

w = width

3w-5 = length

w+w+3w-5+3w-5 = 70

8w - 10 = 70

8w = 80

w = 10

l = 3(10)-5, or 25
