Can you guys help me? :-(

VMariaS [17]

Answer:

$\frac{9}{10}$

Step-by-step explanation:

Find the LCD because like last time, you cannot add or subtract fractions with different denominators.

LCD = 10

Since the second fractions stayed at the same denominator, you will only have to multiply the first fraction.

$\frac{2 * 2}{5 * 2}$

$\frac{4}{10}$

$\frac{4 + 5}{10}$

$= \frac{9}{10}$

Please help solve this

Ne4ueva [31]

Answer:

last option

Step-by-step explanation:

We know that a₁ (or the first term) = 4 so we can rule out the second and third options. d (or the common difference) = 8 (because 4 + 8 = 12, 12 + 8 = 20 and so on) so our answer is the last option.

The length of a rectangle is 5 in. More than 3 times its width. The quadratic function f(x) = x(3x + 5) represents the area of t

True [87]

Answer: Domain of function is $R^{ + }$ or (0, $\infty$ )

Step-by-step explanation:

Assuming x as width of rectangle

so, Width = x

Question says, Length is 5in more than 3 times id width.

we write as Length = 3x+5

Therefore, Area of rectangle will be given function f(x)

f(x) = x(3x+5)

Here, It is important to notice that width and length of rectangle will always be positive values and also, area of rectangle is always positive.

we can write in equation as

$x > 0$

$f(x) > 0$

Thus, Domain of function is $R^{ + }$ or (0, $\infty$ )
