Answer:

D)

DF = 52

AB = 48

Step-by-step explanation:

Use the two lengths of sides already given.

Divide to find the scale factor:

20 / 5 = 4

Scale factor: 4

Now multiply to find the unknown sides:

13 × 4  = 52

12 × 4 = 48

DF = 52

AB = 48

Hope this helped.

Find the missing length indicated..
egoroff_w [7]

Answer:

I think it is 20 but I'm not sure. Sorry if you get it wrong.

Step-by-step explanation:

It's definatly not 4 or 7 because those lengths are too short to be where the question mark is. And 45 is too big for the missing length side.

Thx.

Mark bought a double oven electric range for $1350. He made a 15% down payment and financed the balance, paying $150 a month for
wel
150 x 10 = 1500
10% of 1350 = 135
5% of 1350 = 67.50
15% of 1350 = 202.50

total = 202.50 + 1500 = $1702.50

A) We can pick any two values from the table then can subtract initial value from final value divide by the number of instance which will give us the rate of change.

b) Same with the graph, we take two coordinates and then apply in the formula:
 slope (m) = y2-y1 / x2-x1

c) We can write the equation, by substituting into the formula:
y - y1 = m (x - x1)
Where y-interecpt & slope is most important

d) When, we completely solve the equation, then it gives y-intercept, and first value of the path in the graph is known as initial value

e) In linear interval, difference between any two instances must be same, 'cause they follow the rule of proportionality whereas in non-interval, differnce will be different in magnitude

Hope this helps!

<h2><u>Simplifying</u></h2>

<h3>x - (-6x)</h3>

To determine the answer, the first step is to apply distributive property.

  • x - (-6x)
  • x + 6x

Why it became positive? Notice that - (-6x), there is a negative sign inside and outside the parentheses. Since both of them are negative, we can say that when two negative numbers are multiplied together, it will became positive.

  • x + 6x
  • 7x

<u>Answer:</u>

  • The answer is <u>7x</u>.
