Answer:
Felipe's expression using the Distributive Property can be written as
5 × 28 = 5( 20 + 8)
5 × 28 = (5 × 20) + (5 × 8)
Step-by-step explanation:
Distributive property states that:
a( b + c) = ab + ac
We are told in the question that:
DVDs are on sale for $28 each. Felipe writes the expression 5 × 28 to find the cost in dollars of buying 5 DVDs.
Therefore:
Felipe's expression using the Distributive Property can be written as:
5 × 28 = 5( 20 + 8)
5 × 28 = (5 × 20) + (5 × 8)
Show that the angles A and B are congruent
Answer:
Step-by-step explanation:
The diagram of the sled kite is attached below.
The central part of the kite is square.
We know by the property of a square that all its angles are congruent and equal to 90 degrees.
Therefore:
Angles A and B are congruent.
Answer:
45,45,90
Step-by-step explanation:
3x + 3x + 6x= 180
12x=180
x= 180/12= 15
3x=3×15=45
3x=3×15=45
6x=6×15=90
Answer:
3/4
Step-by-step explanation:
1 1/4 * 3/5
Change the mixed number to an improper fraction
1 1/4 = (4*1+1)/4 = 5/4
5/4* 3/5
The 5's cancel
3/4
Answer:
b). 16.
Step-by-step explanation:
x^2 = 4
We can write this as
x^2 + 0x - 4 = 0
The discriminant (b^2 - 4ac) =
0^2 - 4 * 1* -4
= 16.
