Answer:
Chris have 24 local stamps
Step-by-step explanation:
We are given that The ratio of the number of local stamps to foreign stamps is 1 : 3.
Let the ratio be x
Number of local stamps = x
Number of foreign stamps = 3x
Total Number of stamps =x+3x=4x
We are given that Chris has 96 local and foreign stamps altogether in his collection
So, 4x=96
x=24
Hence Chris have 24 local stamps

Answer:
The Identity Property
Step-by-step explanation:
The identity property for addition tells us that zero added to any number is the number itself. Zero is called the "additive identity." The identity property for multiplication tells us that the number 1 multiplied times any number gives the number itself.
Answer:
Step-by-step explanation:
Answer:
1)
32x^2 - 28x - 15
2)
30x^2 + 54x - 12
Step-by-step explanation:
1.
(8x+3)(4x-5)
Using FOIL
= (8x)(4x) + (8x)(-5) + (3)(4x) + (3)(-5)
= 32x^2 - 40x + 12x - 15
= 32x^2 - 28x - 15
2.
(10x-2)(3x+6)
Using FOIL
= (10x)(3x) + (10x)(6) + (-2)(3x) + (-2)(6)
= 30x^2 + 60x - 6x - 12
= 30x^2 + 54x - 12
