Which equation applies the distributive property?

1 answer:

3 0

The distributive property dictates that:
a(b + c) = ab + ac
Thus,
(0.7 x 0.7) + (0.7 x 0.9) + (0.7 x 0.2)
= 0.7(0.7 + 0.9 + 0.2)
follows the distributive property. The third option is correct.

Two of largest mammals on earth are the blue wale and the African elephant. An adult male blue whale weighs about 170 tonnes or

Liula [17]

Weight is 1.7 × 10^5 kg

Step-by-step explanation:

Step 1: Given that the weight of the blue whale = 170 tonnes
Step 2: Convert the number of tonnes into kg.

⇒ 170 tonnes = 170 × 1000 (1 tonne = 1000 kg)

⇒ 170 tonnes = 17 × 10^4 kg

Step 3: Convert it into standard format, that is with just one decimal point.

⇒ 17 × 10^4 = 1.7 × 10^5 kg (Dividing and multiplying by 10 on both sides)

s = 2j + 3.

For instance, if addie was 5, you could find the sum of their ages by substituting her age into the formula.

s = 2(5) + 3

S = 13

What is the modulus of |9+40i|?

Talja [164]

Answer:

Step-by-step explanation:

We know that complex numbers are a combination of real and imaginary numbers

Real part is x and imaginary part y is multiplied by i, square root of -1

Modulus of x+iy = $\sqrt{x^2+y^2}$

Here instead of x and y are given 9 and 40

i.e. 9+40i

Hence to find modulus we square the coefficients add them and then find square root

|9+49i| = $\sqrt{9^2+40^2} =\sqrt{1681}$

By long division method we find that

|9+40i| =41
