<h2>Answer:</h2>

The product of the expression is:

            20t^2+9t-20

<h2>Step-by-step explanation:</h2>

We have to find the product of two algebraic  expressions which are given in terms of variable t  as:

           (5t-4)(4t+5)

We know that the product of two linear function will result in a quadratic equation i.e. a polynomial of degree 2.

We find the product as follows:

(5t-4)(4t+5)=5t(4t+5)-4(4t+5)\\\\\\i.e.\\\\\\(5t-4)(4t+5)=20t^2+25t-16t-20\\\\\\i.e.\\\\(5t-4)(4t+5)=20t^2+9t-20

Hence, the product is:

        20t^2+9t-20

Determine the measure of the interior angle at vertex C
vladimir1956 [14]

The measure of the interior angle at vertex C is D. 144.

<h3>How to calculate the angle?</h3>

Based on the information given, the angle will be calculated thus:

8x + 8x + 8x + 3x + 3x = (5 - 2) × 180

30x = 540

Divide both side by 30

30x/30 = 540/30

x = 18

Therefore, at vertex C, we have 8x. This will be:

= 8x

= 8 × 18

= 144

Please tell me correct and​
choli [55]

Answer:

\frac{1}{4} or 0.25 (they're the same)

Step-by-step explanation:

First Part:

  1. 4^{3} = 64  
  2. 8^{2} = 64  
  3. 2 = 2  
  4. Multiply them together: 64 × 64 × 2 = 8192

Second Part:

  1. 2^{7} = 128  
  2. 16^{2} = 256  
  3. Multiply them together: 128 × 256 = 32768

Wrap it all up:

  1. 8192 ÷ 32768 = 0.25 = 1/4

I hope this helps!

In the equation Ax + By = C, A and B
Rudik [331]

Answer:

0(x) + BY=c

0 + By = c

By = c

divide both sides by BY

BY/by = c/By

= c/by

Why is it important to calculate the distance between two points on a cartesian coordinate plane?
Gwar [14]

Answer:

Derived from the Pythagorean Theorem, the distance formula is used to find the distance between two points in the plane. The Pythagorean Theorem,

a

2

+

b

2

=

c

2

, is based on a right triangle where a and b are the lengths of the legs adjacent to the right angle, and c is the length of the hypotenuse. The relationship of sides

|

x

2

−

x

1

|

and

|

y

2

−

y

1

|

to side d is the same as that of sides a and b to side c. We use the absolute value symbol to indicate that the length is a positive number because the absolute value of any number is positive. (For example,

|

−

3

|

=

3

. ) The symbols

|

x

2

−

x

1

|

and

|

y

2

−

y

1

|

indicate that the lengths of the sides of the triangle are positive. To find the length c, take the square root of both sides of the Pythagorean Theorem.

c

2

=

a

2

+

b

2

→

c

=

√

a

2

+

b

2

It follows that the distance formula is given as

d

=

(

x

−

x

)

(

y

−

y

)

→

d

=

√

(

x

2

−

x

1

)

2

+

(

y

2

−

y

1

)

2

We do not have to use the absolute value symbols in this definition because any number squared is positive.

A GENERAL NOTE: THE DISTANCE FORMULA

Given endpoints

(

,

y

and

(

, the distance between two points is given by
