21(z+50)= 1,071 distrbultive property

Mathematics

Harman [31]3 years ago
8 0

Answer:

The value of z is 1.

Step-by-step explanation:

Given:

21(z+50) = 1071

We need to solve the problem using distributive property.

Solution:

For the given equation we will apply distributive property;

By Definition of Distributive property which states that;

"The distributive property lets you multiply a sum by multiplying each addend separately and then add the products."

example = a(b+c) = a\times b +a\times c =ab +ac

So we get;

21\times z + 21\times 50 = 1071\\\\21z + 1050 =1071

Now by using Subtraction property we will subtract both side by 1050 we get;

21z+1050-1050=1071-1050\\\\21z=21

Now Dividing both side by 21 by using Division property we get;

\frac{21z}{21}=\frac{21}{21}\\\\z=1

Hence The value of z is 1.

Which method is the most efficient method to use to solve x^2+4x+3=0
Romashka-Z-Leto [24]

Answer:

Factoring

Step-by-step explanation:

To solve the equation x ^ 2 + 4x + 3 = 0, you must apply the factoring method.

You must find two real numbers b and c such that:

b + c = 4

and

b(c) = 3

Then the expression:

x ^ 2 + 4x + 3 = 0 = (x + b)(x + c)

You can prove that:

b = 3\\c = 1

So

x ^ 2 + 4x + 3 = 0 = (x + 3)(x + 1)

(x + 3)(x + 1) = 0

x +3 = 0 or x + 1 = 0

x = -3 or x = -1

What is the slope of a line that passes through the points (4, 2) and (8, 5) *
Illusion [34]

Start with the slope formula.

Slope formula can be read as the second y minus the first

y over the second x minus the first x.

So for this problem, the second y minus the first y would be

5 - 2 and the second x minus the first x would be 8 - 4.

5 - 2 over 8 - 4 is 3/4.

So the slope of the line that passes through these points is 3/4.
