Oxana [17]

Answer:

1. Area of a square = (x^2)^2 = x^4

(each side is x^2, area of a square = side^2

so (x^2)(x^2) = x^4 )

2. when x = 5

area = 5^4 = 625

3. when x = 10

area = 10^4 = 10000

Step-by-step explanation:

Hope its right!

Which equation is equivalent to 7(x-2) = 149? Will give Brainly points

Effectus [21]

Answer:

B. $\log_{7} 149+2 = x$

Step-by-step explanation:

Let $7^{x-2} = 149$ , we proceed to find its equivalent expression by applying logarithm properties:

1) $7^{x-2} = 149$ Given.

2) $\log_{7} 7^{x-2} = \log_{7} 149$ Definition of logarithm.

3) $(x-2)\cdot \log_{7}7 = \log_{7} 149$ $\log_{a} b^{c} = c\cdot \log_{a} b$

4) $x-2=\log_{7}149$ $\log_{a}a = 1$

5) $x = \log_{7}149+2$ Compatibility with addition/Existence of additive inverse/Modulative property

6) $\log_{7} 149+2 = x$ Symmetrical property/Result.

Hence, the right answer is B.

Please, help me :)

60+60 - hour heads up
80x-each hour travels 80miles
And both have a variable (x) that represent the number of hours
Equation:
60+60x=80x
Combine terms:
60=20x
Divide both sides by 20:
X=3
Soooo that means at 3:00pm two trains will be at the same distance from Chicago which is 240 miles
Hope this helps
