<h2>Greetings!</h2><h3>1) If 7g = 315, then to get 1g you simply divide both sides by 7:</h3>

7 ÷ 7 = 1

315 ÷ 7 = 45

So g = 45

<h3> 2) If you divide 87 by h you get 4, you can simply reverse this and divide 87 by 3:</h3>

87 ÷ 3 = 29, so h is 29.

6 times 7 to the second power
Travka [436]
Hello!

To solve this question, we must first add the exponent into the number 7 before multiplying it by the number 6. 

7 to the second power simply means 7x7. 

7x7= 49

Now that the exponent is in the equation, we can multiply 49 by 6 to find your final answer. 

6 x 49 = 294

I hope this helps answer your question! Have a great day!

Tristán wants to build a square garden in his backyard if the garden is going to be 64 ft2 how many feet of material will he nee
Alex777 [14]

Answer:

Tristan will need 32 feet of material for the perimeter of the garden.

Step-by-step explanation:

Given that

Area of square garden = A = 64 square feet

Perimeter = P = ?

We know that for calculation of perimeter, length of side of square is required which is not directly given in the question. The area will be used to calculate length of side and then length will be used to calculate the perimeter.

So,

Area = A = s^2

s is for side

Putting the value of area

64 = a^2

Taking square root on both sides

\sqrt{s^2} = \sqrt{64}\\s = 8\ feet

The length of side is 8 feet.

Perimeter will be:

P = 4*s\\P = 4*8\\P = 32\ feet

Hence,

Tristan will need 32 feet of material for the perimeter of the garden.
