Answer:
x= 1/2 and x= -3
Step-by-step explanation:
Let's solve your equation step-by-step.
2x2+5x−3=0
Step 1: Factor left side of equation.
(2x−1)(x+3)=0
Step 2: Set factors equal to 0.
2x−1=0 or x+3=0
x=
1
2
or x=−3
Answer:
P(milk) = 7/18
P(not milk) = 11/18
Step-by-step explanation:
The bag contains 7 milk and 11 dark chocolates. That means that there are a total of; 7 + 11 = 18 sweets in the bag.
So, when a sweet is selected at random, probability that the sweet is milk is;
P(milk) = number of milk sweets/total number of sweets = 7/18
Probability it is not milk is;
P(not milk) = number that's not milk/total number of sweets = 11/18
Let the number be the variable x
4 times the number is 4x
the sum of 8 and 4 times a number is 28
4x+8=28
4x=28-8
4x=20
x=20/4
x=5
12√18-6√20-3√50-8√45
<em>*Break each radical up into the product of a radical of a perfect square and a second radical*</em>
12(√9*√2)-6(√4*√5)-3(√25*√2)-8(√9*√5)
<em>*Simplify the radicals*</em>
12(3√2)-6(2√5)-3(5√2)-8(3√5)
<em>*Distribute*</em>
36√2-12√5-15√2-24√5
<em>*Combine like terms</em>*
21√2-36√5
