Express the ratio of the area of triangle abc to the area of triangle edc

Yanka [14]

Given :

Two similar triangle.

To Find :

The ratio of the area of triangle abc to the area of triangle edc.

Solution :

ΔABC ~ ΔAPQ (AA criterion for similar triangles)

Since both the triangles are similar, using the theorem for areas of similar triangles we have :

$\dfrac{Area \ of \ \Delta ABC}{Area \ of \ \Delta EDC} = \dfrac{AC}{EC}\\\\\dfrac{Area \ of \ \Delta ABC}{Area \ of \ \Delta EDC} = \dfrac{20+8}{20}\\\\\dfrac{Area \ of \ \Delta ABC}{Area \ of \ \Delta EDC} = 1.4$

Therefore, ratio of area of triangle is 1.4 .

If both the zeroes of a polynomial x2+4x+2p are real and equal then find the value of p.

creativ13 [48]

Answer:

p = 2

Step-by-step explanation:

If both zeroes at equal, they must be the negative half of the second term. As this term is 4, $-\frac{4}{2} =-2$ . This means that each of the zeroes must be -2. This means that the polynomial must be $(x+2)^2$

This simplifies to $x^2+4x+4$

From the intial problem, we can set up an equation and solve for p. $2p=4\\\\p=2$

Dmitry [639]

Answer:

Benny started with 74 cards.

Step-by-step explanation:

To find the answer, the first part with Benny buying eight more baseball cards is unnecessary information. Since his dog ate exactly half of his baseball card collection and he was left with 37 cards, he would've had 74 cards to start with.

Which of the following is equal to the rational expression when x does not equal -3 x^2-9/x+3

mestny [16]

Answer:

x - 3

Step-by-step explanation:

Given

$\frac{x^2-9}{x+3}$

Note that x² - 9 is a difference of squares and factors as

x² - 9 = (x + 3)(x - 3), thus

$\frac{(x+3)(x-3)}{x+3}$

Cancel the x+ 3 factor on the numerator/ denominator leaving

x - 3 ← in simplified form
