Which sum or difference is modeled by the algebra tiles?

Answer:

42

Step-by-step explanation:

To fine the value of the expression 4m-6 when m = 12, we can plug our value for x (12) into or expression, and then simplify.

So first,

4(12) - 6

Multiply our 4 and 12 ==>

48 - 6

Now subtract the 6 ==>

42

And we have our answer!

Hope this helped!

Rewrite the 3 fractions to have a common denominator:

1/4 = 5/20

2/5 = 8/20

3/4 = 15/20

Now solve:

5/20 - 8/20 + 15/20 = 12/20

12/20 can simplify to 3/5

Step-by-step explanation:

log27(9)

Factor the number: 27=3³

= log3³(9)

Apply log rule: loga^b(x) - 1/b loga(x).

log3³(9) =1/3 log3³(9)

=1/3 log3³(9)

Factor the number: 9=3²

=1/3 log3³(3²)

Apply log rule: loga(a^b) =b

log3 (3²) =2

Answer:

1,440

Step-by-step explanation:

The amount will be equal to $14478.22.

Compound interest is the interest levied on the interest. The formula for the calculation of compound interest is given as:-

A = P (1+R/2)^2t

Where, A = Amount after 6 years = $26,000; P = Amount invested now; R = Annual rate of earning = 10% = 0.06; t = time = 6 years.

Substituting;

[tex]26000 = P(1+\dfrac{0.1}{2})^{2*6}=P(1.7958)[/tex]

Therefore, P = 26000/1.7958 = $14478.22

Thus amount will be equal to $14478.22.

Red line:

[tex](5, 0), (0, -5) \\m = \frac{\triangle y}{\triangle x} = \frac{0 - (- 5)}{5 - 0} = \frac{5}{5} = 1\\\text{y-intercept (c) is when x = 0}\\x = 0 \rightarrow y = -5\\y = mx + c\\y = 1x - 5\\y - x = -5\\-y + x = 5\\x - y = 5[/tex]

Step-by-step explanation:

a)

the total length of the outer or also only the inner perimeter ?

I assume the second case. but it is not difficult to change it to the outer perimeter case (per the information of b).

the total length consists of a straight side and 2 radius (left and right) of the end circles.

a radius is half the diameter, so 2×radius = 1 diameter.

so,

400 = length + 49

length = 400 - 49 = 351 m

the length of the straight sides is 351 m.

b)

the difference in length between both perimeters bases only on the difference in length of the circumference of the end circles. the lengths of the straight sides remain the same, not matter if outer or inner perimeter.

the circumference of 2 half circles is the circumference of 1 whole circle.

the circumference of a circle is

2×pi×r = pi×diameter

in our case for the inner perimeter

pi×49 = 153.93804... m

for the outer perimeter the radius and therefore the diameter changes : we have to add 6×1.5 m = 9 m on both sides of the circle

so, the radius of the outer circles is 9 m longer and the diameter 9×2 = 18 m longer : 49 + 18 = 67 m

so, we get for the outer circle perimeter

pi×67 = 210.4867078... m

therefore, the difference in the length of outer and inner perimeter is

210.4867078... - 153.93804... = 56.54866776... m
