Consider the polynomial below.

Mathematics
1 answer:
kotykmax [81]3 years ago

Answer:

(-4x - 2)(-5x) + (-4x - 2)(3)  

Step-by-step explanation:

Your polynomial is

(-4x - 2)(-5x + 3)

The distributive property states that

a(b + c) = ab + ac

Let a = -4x - 2.  Then

(-4x - 2)(-5x + 3) = a(5x + 3) = a(-5x) + a(3)

Substitute the value of a.

a(-5x) + a(3) = (-4x - 2)(-5x) + (-4x - 2)(3)

You have just distributed the first binomial (-4x - 2) among the terms of the second binomial.

aev [14]

Answer:

y=1

x=-5

Step-by-step explanation:

3x+y=-14

4x+4y=-16

y=-3x-14

4x+4y=-16

y=-3x-14

4(-3x-14)+4x=-16

y=-3x-14

-8x-56=-16

y=-3x-14

-8x=40

y=-3x-14

x=-5

y=1

x=-5

Solve for m please. No explanation needed thank you.
liq [111]

Answer is below.

<em>(Note to asker: Lack of explanations can get my answer deleted)</em>

<em />

<u><em>Step 1</em></u>

We'll to isolate the variable, but to do that, get rid of the coefficient that multiplies it.

To do that, divide both sides by 22.

\frac{22m}{22}=\frac{22}{10}

<em><u>Step 2.</u></em>

Now we have divided both sides by 22, but we'll need to reduce the fraction \frac{22m}{22}.

We can reduce the fraction by dividing the factors that are in the numerator and denominator.

That being said, 22 appears both in the numerator and denominator.

\frac{22m}{22}=m=\frac{2\times5}{2\times11}

<u><em>Step 3</em></u>

Now, for \frac{2\times5}{2\times11}, we'll need to reduce it to the lowest terms. Like in the 2nd step, we'll divide factors that are in the numerator and denominator.

That being said, 2 appears both in the numerator and denominator.

Hence, M = 5/11

Applying the concepts. Need help finding the value.
luda_lava [24]

we can use formula

log_ab=\frac{ln(b)}{ln(a)}

log_23*log_34*log_45*log_56*log_6 7 *log_7 8=\frac{ln(3)}{ln(2)}*\frac{ln(4)}{ln(3)}*\frac{ln(5)}{ln(4)}*\frac{ln(6)}{ln(5)}*\frac{ln(7)}{ln(6)}*\frac{ln(8)}{ln(7)}

now, we can cancel terms

and then we can simplify it

log_23*log_34*log_45*log_56*log_6 7 *log_7 8=\frac{ln(8)}{ln(2)}

log_23*log_34*log_45*log_56*log_6 7 *log_7 8=\frac{ln(2^3)}{ln(2)}

log_23*log_34*log_45*log_56*log_6 7 *log_7 8=\frac{3ln(2)}{ln(2)}

now, we can simplify it

and we get

log_23*log_34*log_45*log_56*log_6 7 *log_7 8=3...........Answer

the sum of two numbers is 44. the smaller number is 20 less than the larger number. what are the numbers?
Troyanec [42]
Sum means add
x and y are the numbers
sum i 44
x+y=44

smaller s 20 les than larger
x=20+y
or
y=20+x
doesn't matter, just pick one
x=20+y

substue 20+y for x since they are equal
x+y=44
(20+y)+y=44
20+y+y=44
20+2y=44
subtract 20 from both sides
2y=24
divide by 2
y=12
subsitue
x=20+y
x=20+12
x=32

the numbers are 12 and 32
