Answer:

-4

Step-by-step explanation:

Factor by the numbers from left to right.

$64^\frac{1}{3}$

$64=4^3$

$(\frac{4}{3})^\frac{1}{3}=4^3^*^\frac{1}{3}=4$

It changes to positive to negative.

-4

-4 is the correct answer.

Factoring PolynomialsFind the roots of a quadratic equation with leading coefficient greater than 1

musickatia [10]

$4v^2+12v+9=0$

on this point we can use the formula to factor

$v=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}$

where a is 4, b is 12 and c is 9

replacing

$v=\frac{-(12)\pm\sqrt[]{(12)^2-4(4)(9)}}{2(4)}$

and solving

$\begin{gathered} v=\frac{-12\pm\sqrt[]{144-144}}{8} \\ \\ v=\frac{-12\pm\sqrt[]{0}}{8} \\ \\ v=-\frac{12}{8}=-\frac{3}{2} \end{gathered}$

The root is

$-\frac{3}{2}$

then the polynomial has one root -3/2 if we rewrite the polynomial is

$(v+\frac{3}{2})^2=0$

$(2v+3)^2=0$

Two farmers each have triangular plots of land in the diagram below with approximate values shown for lengths in feet

Ray Of Light [21]

Answer:

a) Plots are similar
b) x= 5577 feet

Step-by-step explanation:

Refer to attached

<h3>Question</h3>

a) Are the plots of land similar?
b) Find to the exact value of x and rounded to the nearest tenth?

<h3>Solution</h3>

The small triangle have missing angle of 180° - (52° + 58°) = 70°

This is indicating both triangles have same 3 angle measures.

Since all angles are same, the triangles are similar.

Corresponding sides, against corresponding angles are:

6180 and 8240
x and 7436

As per property of similarity, the ratio of corresponding sides is same

6180/8240 = x/7436
x = 6180*7436/8240
x = 5577 feet
