Step-by-step explanation:

$2x+15= 145°$

( vertically opposite angles)

$2x=145-15 = 130$

$x = \frac{130}{2}$

$x = 65$

The formula for finding the perimeter of a rectangle is P = 2L + 2W. If a rectangle has a perimeter of 68 inches and the length

Artemon [7]

Answer:

Width = 10 inches

Step-by-step explanation:

Given the perimeter of a rectangle of 68 inches, and a length that is 14 inches longer than its width.

We can establish the following values to help us solve for the width of a rectangle:

Perimeter (P) = 68 inches

Length (L) = 14 + W inches

Width (W) = unknown

<h3 /><h3><u>Solve for the Width (W)</u></h3>

P = 2(L + W) ⇒ This is the same as P = 2L + 2W, except that 2 is factored out from the right-hand side.

Divide both sides by 2:

$\displaystyle\mathsf{\frac{P}{2}\:=\:\frac{2(L\:+\:W)}{2}}$

$\displaystyle\mathsf{\frac{P}{2}\:=L\:+\:W}$

Substitute the value of the Perimeter and the length (L) into the formula:

$\displaystyle\mathsf{\frac{68}{2}\:=14\:+W\:+\:W}$

Combine like terms on the right-hand side, and simplify the left-hand side of the equation:

$\displaystyle\mathsf{34\:=14\:+2W}$

Subtract 14 from both sides:

34 - 14 = 14 - 14 + 2W

20 = 2W

Divide both sides by 2 to solve for the width (W):

$\displaystyle\mathsf{\frac{20}{2}\:=\:\frac{2W}{2}}$

W = 10 inches

Therefore, the width of the rectangle is 10 inches.

<h3 /><h3><u>Double-check:</u></h3>

Verify whether the derived value for the width is correct:

P = 2L + 2W

68 = 2(14 + 10) + 2(10)

68 = 2(34) + 20

68 = 48 + 20

68 = 68 (True statement).

Thus, the length of the rectangle is 34 inches, and the width is 10 inches.

Using only the values given in the table for the function f(x) = –x3 + 4x + 3, what is the largest interval of x-values where th

Bas_tet [7]

Answer:

the largest interval of x values where f(x) is increasing is (-1,1).

Step-by-step explanation:

$f(x)=-x^3+4x+3$

the domain of f(x) is all real numbers.

As we can conclude from the table that the function f(x) is decreasing from (-3, -1) and the function is increasing from (-1, 1) .

Graphically we can also show this that for the x-values in (1,-1) function is increasing.

Answer: The correct answer is: [C]: " $15^{(7/4)}$ " .

____________________________________

Step-by-step explanation:

____________________________________

Note the property for square roots in exponential form:

_____________________________________

→ $\sqrt[a]{(b)^ c}$ ; ↔ b $b^{(c/a)}$ ;

{ $a\neq 0$ ; $[a^{(b/c)}]\neq 0$ ; $c\neq 0$ .}.

_____________________________________

As such, given:

→ $\sqrt[4]{(15^7)}$ ;

a = 15, b = 7, c = 4 .

→ $\sqrt[4]{(15^7)}$ ; ↔ $15^{(7/4)}$ ;

→ which corresponds to:

_____________________________________

Answer choice: [C]: " $15^{(7/4)}$ " .
