Today, isaac needs to walk his dog, water the garden, and feed his fish. d dd is the number of minutes it takes to walk his dog, g gg is the number of minutes it takes to water the garden, and f ff is the number of minutes it takes to feed his fish. the expression g + ( d + f ) g+(d+f)g, plus, left parenthesis, d, plus, f, right parenthesis describes the total number of minutes it takes isaac to do all three tasks. we can also use the expression ( g + d ) + f (g+d)+fleft parenthesis, g, plus, d, right parenthesis, plus, f to represent the same quantity.

don't know sorry bru

step-by-step explanation:

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
