Answer:

-5 x^5 - 5 x^4 + 6 x^3 - x^2 - 7 x + 20

Step-by-step explanation:

(2x^5+x^3−3x^4−x+8)−(7x^5+2x^4−12+6x−5x^3+x^2)

Distribute the minus sign

(2x^5+x^3−3x^4−x+8)−7x^5-2x^4+12-6x+5x^3-x^2

Put them in order from largest exponent to smallest exponent

2x^5−7x^5−3x^4-2x^4+5x^3+x^3-x^2-6x−x+8+12

Combine like terms

-5x^5 -5x^4 +6x^3 -x^2 -7x +20

Standard form is from largest exponent to smallest exponent

Find AB<br><br>please help :-)​
drek231 [11]

Answer:

Therefore,

l(AB) = 15 units

Step-by-step explanation:

Given:

AD = DC

angle DBA = angle DBC = 90°

AB = 5x

CB = 4x - 3

To Find:

AB = ?

Solution:

In  Δ ABD and Δ CBD

AD ≅ DC     ……….{Given}

∠ DBA ≅ ∠ DBC      …………..{measure of each angle is 90° given}

DB ≅ DB                  ....……….{ Reflexive property}

Δ ABD ≅ Δ CBD      ..........….{By Hypotenuse Leg Theorem}

∴ AB ≅ CB               ..............{corresponding sides of congruent triangles}

on substituting the values we get

5x=4x+3\\\\5x-4x=3\\\\\therefore x =3

Now we require AB

AB=5x\\\\AB=5\times 3\\\\AB=15\ units

Therefore,

l(AB) = 15 units

Write one digit on each side of 10 to make a four digit multiple of 72. How many different solutions does this problem have? The
Viefleur [7K]

If we write 4 to each side of 10, we will get a four digit number 4104, which is a multiple of 72.

To find out other possible solutions, first start with 1 in front of 10.

Now, divide 110 by 72.

The remainder is 38.

We are going to put one more digit after 10.

So, let us check if there is any three digit number whose first two digits are 38 and which is a multiple of 72.

There is no such number since 5 × 72 = 360 and 6 × 72 = 432.

So, there is no four digit number whose first three digits are 110 and which is a multiple of 72.

If we try like this, we can find 4104 is the only solution.
