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

an adult blue whale weighs 120 tons. a baby whale weighs 1/40 of the weight of the adult blue whale. how many pounds does the ba

sveticcg [70]

First of all, remember that one ton= 2000 pounds.

Since the adult whale weighs 120 tons, multiply this by 2000 to find the number of pounds. 120*2000=240,000 pounds.

A baby whale weighs 1/40 of the adult whale's weight. Multiply 1/40 times 240,000 to find the total weight in pounds of the baby whale. $\frac{240000}{1} * \frac{1}{40} = \frac{240000}{40} = 6000$

The baby whale weighs 6000 pounds.
