2((x+2)(x+2)}-4=28
2{x^2 + 4x + 4}-4=28
2x^2 +4x=28
2(x^2+2x)=28
x^2+2x=28/2
x^2+2x=14
Answer:5a-30=45
Step-by-step explanation:
So something times 5 minus 30 will give you 45
The equation represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake is
.
Given
The magnitude, M, of an earthquake is defined to be M = log StartFraction I Over S EndFraction, where I is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and S is the intensity of a "standard" earthquake, which is barely detectable.
<h3>The magnitude of an earthquake</h3>
The magnitude of an earthquake is a measure of the energy it releases.
For an earthquake with 1,000 times more intense than a standard earthquake.
The equation represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake is;

Hence, the equation represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake is
.

Answer:
Step-by-step explanation:
24x = 8*3*x
16 = 8* 2
Greatest common factor = 8
24x - 16 = 8(3x - 2)
