Step-by-step explanation:
<em>zero product property (Angela)</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em> (Angela)</em>
<em>3x² + 10x = 0</em>
<em>x(3x + 10) = 0</em>
<em>x = 0 => x₁ = 0</em>
<em>3x + 10 = 0 => 3x = - 10 => x₂ = - 10/3 = - 3 1/3</em>
<em>Good luck !</em>
30 + 8 = 38 desks
38 x 4 = 152 legs
If you did not add those eight desks then you will have 120 legs.
So, the amount of legs will go up by 32 if you add 8 more desks.
Answer:
20
Step-by-step explanation:
Step 1: 4 = 20% × Y
Step 2: 4 = 20/100 × Y
Multiplying both sides by 100 and dividing both sides of the equation by 20 we will arrive at:
Step 3: Y = 4 × 100/20
Step 4:Y = 4 × 100 ÷ 20
Step 5: Y = 20
