Answer:
x = 7 units
Step-by-step explanation:
Write and solve an equation of ratios, as follows:
5 cm 3 cm
------------------ = ------------------------
(40 + 5) cm (3 + 2x + 10) cm
This simplifies to:
5 3
-------- = -----------
45 2x + 13
Solve for x. Cross-multiplying, we get:
10x + 65 = 135, or x = 7
So x = 7 units.
A = 0 (or) B = 0
Solution:
The zero product principle is most probably used to solve a quadratic equation by factoring the factors.
Let us know the definition of zero product principle.
Zero product principle:
The zero product principle states that if the product of two factors is zero then at least one of the factors must be zero.
This means that if AB = 0, then A = 0 (or) B = 0.
Hence, The zero-product principle states that
if AB = 0, then A = 0 (or) B = 0.
Correct answer should be 1/2
Answer:

Step-by-step explanation:
Answer:
6
Step-by-step explanation:
All you have to do is divide -4 on both sides and you get 6!
-4x= -24
/-4 /-4
x = 6
I hope this helps, and have a great day!
