Apply and extend previous understandings of multiplication
to multiply a fraction by a whole number. Solve word problems involving
multiplication of a fraction by a whole number, e.g., by using visual fraction models.
Answer:
<h2>-5*3 -8*-5 +2</h2><h2>= -15 +40 +2</h2><h2>= 27</h2>
Answer:
A) -8x^2 - 26x - 15
Step-by-step explanation:
(4x + 3)(-2x - 5)
FOIL
first: 4x*-2x = -8x^2
outer : -5*4x = -20x
inner: -2x*3 = -6x
last: -5*3 = -15
Add these together
-8x^2 -20x-6x -15
-8x^2 -26x-15
The second one, 69/24 = 23/8 and cannot be simplified further
