Answer:

log 7

Step-by-step explanation:

We have to find the value of the logarithmic expression

Log(14/3) + log(11/5) - log(22/15)

We know the formula

log a + log b = log (ab)

Using this formula, we have

log(14/3) + log(11/5) - log(22/15)

=log ( 14/3 × 11/5) - log(22/15)

= log (154/15)- log(22/15)

Now, use the formula log a - log b = log (a/b)

= log (154/15×15/22)

On simplifying, we get

= log 7

Thus, the shoplifted form is log 7

I need to know the area
nadya68 [22]

Answer:

67.5 units²

Step-by-step explanation:

We can break this problem down in two parts: The upper triangle and the lower trapezoid.

The upper triangle:

Use the formula \frac{1}{2} (b)(h) to compute the area of the triangle. Base = 10 and Height = 7.

1/2 (10)(7)

1/2 (70)

=35 units².

The lower trapezoid:

Use the formula \frac{1}{2}(base_{1} + base_{2}) (height) to compute the area of the trapezoid. Base 1 = 10, Base 2 = 3 and Height = 5.

1/2 (10 + 3)(5)

1/2 (13)(5)

1/2 (65)

=32.5 units²

So, add the two areas of each shape:

35 + 32.5 = 67.5 units².

Write an equation: The sides of a rectangle are x and ( x - 4 ). The perimeter is 87
Svetlanka [38]

The perimeter of a rectangle, is all of the sides added up.

In a rectangle, there are two widths (right and left), and two lengths (up and down)

So:

Perimeter = 2 × width + 2 × length.

To get the equation we just substitute in the values that we are given:

length = (x)

width = (x - 4)

perimeter = 87

So just put these values into:  perimeter = 2 × width + 2 × length:

87  =  2(x) + 2(x - 4)

_____________________________

Answer:

The equation is:       87 = 2(x) + 2(x - 4)

<em>(note: this can be simplified down like so:</em>

<em>87 = 2x + 2x - 8</em>

<em>87 = 4x - 8</em>

<em>95 = 4x</em>

23.75 = x
