Como se multiplican polinomios

I hope you speak english, because although i understood your question I don't know enough spanish to respond in it. You multiply polynomials by multiplying each part of one polynomial by all the other parts of the others, and then adding it all. For example: (ax+b) * (x+c) = (ax*x)+(ax*c)+(b*x)+(b*c) = $a x^{2} + acx + bx+bc$

Comprehende?

So you start by subtracting 3 from 35, which is 32. 32/8 = 4. So three years ago, Tim's son was 4 and Tim was 32. The percentage is about 13%

a garden is 18 feet 3 inches long and 10 feet 8 inches wide. the amount of fencing needed to enclose the garden is Need help and

Anna [14]

Answer:

$\boxed{57ft 10in}$

Step-by-step explanation:

<em>Hey there!</em>

Well if the length is 18 and 3 inches we need to find the sum of both lengths,

18ft 3in + 18ft 3in = 36ft 6in

Width- 10ft 8in + 10ft 8in = 20ft 16 in -> 21ft 4in

l + w = 57ft 10in

<em>Hope this helps :)</em>

How do I solve for the missing lengths?

Advocard [28]

Answer:

Part 4) $ER=3\ units$

Part 5) $DF=9\sqrt{10}\ units$

Part 6) $DE=30\ units$

Step-by-step explanation:

Part 4) Find ER

we know that

In the right triangle ERF

Applying the Pythagorean Theorem

$EF^2=ER^2+RF^2$

substitute the given values

$(3\sqrt{10})^2=ER^2+9^2$

solve for ER

$ER^2=(3\sqrt{10})^2-9^2$

$ER^2=90-81\\ER^2=9\\ER=3\ units$

Part 5) Find DF

we know that

In the right triangle DRF

Applying the Pythagorean Theorem

$DF^2=DR^2+RF^2$

substitute the given values

$DF^2=27^2+9^2$

$DF^2=810\\DF=\sqrt{810}\ units$

simplify

$DF=9\sqrt{10}\ units$

Part 6) Find DE

we know that

$DE=DR+RE$ ----> by segment addition postulate

we have

$DR=27\ units\\RE=ER=3\ units$

substitute

$DE=27+3=30\ units$

Davis is building a wooden bench. He has 2 3/5feet of lumber in his garage and buys 8 1/2feet of lumber at the store. How many t

Firdavs [7]

Answer:

Below.

Step-by-step explanation:

2 3/5 + 8 1/2

= 2 + 8 + 3/5 + 1/2

= 10 + 3/5 + 1/2

The LCM of 5 and 2 is 10 so we get:

10 + 6/10 + 5/10

= 10 + 11/10

= 10 + 1 1/10

= 11 1/10 feet.

A golfer is standing on a tee with a green in a valley below. If the tee is 43 yards higher

Ksivusya [100]

Answer:

$13.65^0.$

Step-by-step explanation:

Given,

Height of tee, H = 43 yard

Direct distance of the hole is, D = 177 yards

Now, Angle of depression of tee

$\tan \theta = \dfrac{H}{D}$

$\tan \theta = \dfrac{43}{177}$

$\tan \theta =0.2429$

$\theta = 13.65^\circ$

Hence, angle of depression from tee to the green is $13.65^0.$
