Multiply the coefficient of x^2 in the original

Answer:

(a + b)(c + d), ac+ ad+ bc + bd, 2x squared + x - 3 or (2x+ 3)(x -1).

Step-by-step explanation:

For an expression of the form (a + b)(c + d), the expanded version is ac + ad + bc + bd, in other words everything in the first bracket should be multiplied by everything in the second. Factorising is the reverse of expanding brackets, so it is, for example, putting 2x² + x - 3 into the form (2x + 3)(x - 1).

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we know that "Angle opposite to greater side is smaller or angle opposite to smaller side is larger".

So, ∠AOD is opposite to side 'AD' which is equal to 8.11

Similarly, ∠AOB is opposite to side 'AB' which is equal to 8.

So, ∠AOB>∠AOD

Hence, Option 'B' is correct.

A) Find the distance of line segment PR. Round answer to the nearest tenth. B) Find the distance around the park (perimeter).

juin [17]

Answer:

A. $PR = 80.6 yd$

B. Perimeter = 190.6 yd

Step-by-step explanation:

A. Distance between P(10, 50) and R(80, 10):

$PR = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

$PR = \sqrt{(80 - 10)^2 + (10 - 50)^2}$

$PR = \sqrt{(70)^2 + (-40)^2}$

$PR = \sqrt{4,900 + 1,600}$

$PR = \sqrt{6,500}$

$PR = 80.6 yd$ (nearest tenth)

B. Distance around the park = Perimeter = PR + PQ + QR

PR = 80.6 yd

PQ = |50 - 10| = 40 yd

QR = |80 - 10| = 70 yd

Perimeter = 80.6 + 40 + 70

Perimeter = 190.6 yd
