Answer:

The place value of each digit is 10 times of the place value of left digit and 1/10 times of the place value of right digit.

Step-by-step explanation:

The given number is 9,999,999.

Place values of each digit from left to right are

Place value of first 9 is $9=9\times 1,000,000=9,000,000$

Place value of second 9 is $9=9\times 100,000=900,000$

Place value of third 9 is $9=9\times 10,000=90,000$

Place value of fourth 9 is $9=9\times 1,000=9,000$

Place value of fifth 9 is $9=9\times 100=900$

Place value of sixth 9 is $9=9\times 10=90$

Place value of seventh 9 is $9=9\times 1=9$

The place value of each digit is 10 times of the place value of left digit and 1/10 times of the place value of right digit.

A quadratic equation is shown: x2 + 18x + 76 = 0 Which of the following is the first correct step to write the above equation in

tia_tia [17]

Answer:

x^2 + 18x + 76 + 5 = 0 + 5

Step-by-step explanation:

The first step is to determine the constant that is needed to be able to write the expression in the desired form. That constant is the square of half the x-term coefficient: (18/2)^2 = 9^2 = 81.

The constant that is present is 76, which is 5 fewer than the needed constant, so the "first step" is to add 5 to both sides of the equation:

x^2 + 18x + 76 + 5 = 0 + 5

Then the next step would be to write the left side as a square:

(x +9)^2 = 5 . . . . . . . p = -9; q= 5

Given: Quadrilaterals ABCD ~ EFGH , with measure of angle A = 47 degrees, measure of angle B = 39 degrees, and measure of angle

kaheart [24]

Answer:

The answer is below

Step-by-step explanation:

Two polygons are said to be congruent if they have the same size and shape that is their corresponding angles and sides are equal.

Hence since Quadrilaterals ABCD is congruent to EFGH, then their corresponding angles and sides are equal.

In quadrilateral ABCD:

∠A + ∠B + ∠C + ∠D = 360° (sum of angles in a quadrilateral)

Substituting:

47 + 39 + 112 + ∠D = 360

∠D + 198 = 360

∠D = 360 - 198

∠D = 162°

The image of Quadrilaterals ABCD and EFGH is not given but let us assume that they have the same orientation, hence:

∠A = ∠E = 47°

∠B = ∠F = 39°

∠C = ∠G = 112°

∠D = ∠H = 162°

A = L^2
A = L^2 = 2^2 + 4^2 (Pythagorean’s theorem)
A = L^2 = 20
Therefore the area of the square is 20 units square.
