Solve your inequality step-by-step.

7(x+4)>0

Simplify both sides of the inequality.

7x+28>0

Subtract 28 from both sides
.
7x+28−28>0−28

7x>−28

Divide both sides by 7.

7x/7 > −28/7

x > −4

For question 1, just plug in -2 as <em>h.

</em> $-2(-2)^2-(-2)+2$
<em>
</em>You would get...

$h(-2)=-4$
<em>
</em>Hope this helped! <em>-4, or option 1, is correct!</em><em>

(2x-1)(x+4)=0

Step-by-step explanation:

A random zero property of multiplication is taken to find the solution

(2x-1)(x+4)=0

consider a=2x-1 and b=x-4 a.b=0

either a or b or both must be 0

equating both the equations

2x-1=0 or x=4=0 x-4=0

2x-1=0 x=4

2x=1

x=1/2

substitute the values of x in the main equation

[2(1/2)-1][(1/2)+4]=0
