There are two parts to this problem we need to acknowledge.

First, we need to multiply using the distributive property, or FOIL.

-2x(6x^4 - 7x^2 + x - 5)

Multiply -2x by each term.

<h3>-12x^5 + 14x^3 - 2x^2 + 10x</h3>

Now, fortunately, the expression is already in standard form.

Standard form of a polynomial is where the term of the largest degree is listed first, and as the polynomial continues from left to right, the degree decreases per term.

The highest degree is 5, and the expression is already listed in standard form as the degrees go: 5, 3, 2, 1.

PLEASE HELP! HELP!<br> Plot the points (−3, 0) and (3, 5) on the coordinate plane.
iren [92.7K]

(Image below)

Keep in mind that the first number in a coordinate is always on the x-axis (the horizontal line) and the second number is on the y-axis (the vertical line).

If the question asks us to plot (-3, 0), we need to find -3 on the horizontal line and find 0 on the vertical line.

Since 0 means that we go 0 units up, we can just plot the point at -3 on the x-axis.

Next, we need to plot (3, 5). First, let's find the first coordinate by locating 3 on the horizontal axis. Now, we need to find 5 up from that point, because our y-coordinate is 5.

Find the ragio p:r if p:a=1:2, a:b=2:3, b:c=5:1, c:r=3:2​
MaRussiya [10]

Answer:

p : r = 5 : 2

Step-by-step explanation:

Expressing the ratios in fractional form, then

\frac{p}{r} = \frac{p}{a} × \frac{a}{b} × \frac{b}{c} × \frac{c}{r}

  = \frac{1}{2} × \frac{2}{3} × \frac{5}{1} × \frac{3}{2}

   = \frac{30}{12}

  = \frac{5}{2}

Thus ratio p : r = 5 : 2

Find length of BA don’t answer if you’re a fake bot
Evgen [1.6K]

Answer:

BA = 22.57

Step-by-step explanation:

perimeter = 60

2BZ + 2ZA = 60

BZ + ZA = 30,    BZ = 30 - ZA

tan 25° = 0.4663

0.4663 = ZA/BZ = ZA/(30 - ZA)

multiply both sides by (30 - ZA):

0.4663(30 - ZA) = ZA

simplify:

13.99 -0.4663ZA = ZA

add 0.4663ZA to each side:

13.99 = 1.4663ZA

divide both sides by 1.4663:

ZA = 9.54

BZ = 30 - 9.54 = 20.46

BA² = 9.54² + 20.46²

BA² = 509.62

BA = 22.57
