A banana has 80 calories. This is 5 calories less than one seventh of the calories in a banana split. How many calories in a ban
viva [34]
The answer is 85 times 7. Since the banana was 5 less then the split, the split is 5 more which is 85 calories but then it says it is also 1/7 of the whole split. So you simply multiply 85 and 7 because 85 was only 1/7 of the total banana split

The product of -3 and the square of a number decreased by 8.
Jet001 [13]

Answer:

n^{2}(-3) -8

Step-by-step explanation:

So the "product of" means the answer to a multiplication problem. That means -3 is being multiplied by a number which is squared. I used the variable "n" for number but you could use any letter you want.

This is what we have so far,

n^{2} \\ x -3 or n^{2}(-3)

The term decreased means to reduce or subtract. Which means we are left with....

n^{2}(-3) -8

Hope that helps and have a great day!

5. Combining like terms is similar to adding and subtracting whole numbers because you just add/subtract the numbers with the same variables. It's different because in normal adding and subtracting, you can do it with any whole numbers. But with combining like terms you have to make sure that each term has the same variable or else you can't add/subtract them.

Correct answer is A.

(x^2+4x-3)(2x^2+x+6)
\\=x^2(2x^2+x+6)+4x(2x^2+x+6)-3(2x^2+x+6)
\\=2x^4+x^3+6x^2+8x^3+4x^2+24x-6x^2-3x-18
\\=2x^4+x^3+8x^3+6x^2+4x^2-6x^2+24x-3x-18
\\=2x^4+9x^3+4x^2+21x-18

Answer:

x = 6

Step-by-step explanation:

You use trig to find the hypotenuse of the first triangle. 4^2 + 3^2 = c^2. Then you get c = 5. SInce 10 is 2 times greater than 5 you multiply 3 by 2 and get 6. Hope that helps.
