What is the missing constant term in the perfect square that starts with x^2 -20x

Mathematics
1 answer:
lidiya [134]3 years ago
7 0

Answer:

Missing constant: 100

Step-by-step explanation:

perfect square  (a - b)^2 = a^2 - 2ab + b^2

In this case

20x = 2 * x * 10

and

10^2 = 100

so

(x - 10)^2 = x^2 - 20x + 100

What is the answer? To this question
lianna [129]

Answer:

x = 5

Step-by-step explanation:

In a parallelogram, the diagonals bisect each other.

Therefore,

4x - 5 = 3x

4x  = 3x + 5

4x - 3x = 5

x = 5

Questions:
My name is Ann [436]

The  solution to the expressions given are;

9 -9t/ 12 - 5t

a. 20/ 169

b. -170/ 169

c.  386/ 169

d.  -10/ 169

<h3>How to solve the expressions</h3>

Given:

\frac{9 - 19t}{12 - 5t}

We can see that both variables in the numerator and denominator have no common factor, thus cannot be factorized further

a. \frac{203}{169} - \frac{183}{169}

First, let's find the lowest common multiple

LCM = 169

= \frac{203 - 183}{169}

= \frac{20}{169}

= 20/ 169

b. \frac{13}{119} - \frac{183}{119}

The lowest common multiple is 119

= \frac{13 - 183}{119}

substract the numerator

= - 170/ 119

c. \frac{203}{169} - \frac{183}{169}

The lowest common multiple is 169

= \frac{203 + 183}{169}

= 386/ 169

d. \frac{9}{169}- \frac{19}{169}

The lowest common multiple is 169

= \frac{9 - 19}{169}

= - 10/ 169

Thus, we have the solutions to be 9 -9t/ 12 - 5t, 20/ 169, -170/ 169, 386/ 169, -10/ 169 respectively.
