B=48/7 you simplify 7/b(b) to 7b/6
Then multiply both sides by 6 so 8 x 6 =7b then simplify 8 x 6 =48
And divide both sides by 7 48\7 then switch sides b=48/7
If he mass is 10 then the volume is 100
Answer:
32.5 square feet
Step-by-step explanation:
The formula for a trapezoid is a= 1/2*(b1+b2)*h. B1 and b2 would represent the two bases given and therefore doesn't matter what order you put them in. Plug in all values into the equation and you'll get 1/2*(5+8)*5 then 1/2*(13)*5. Next simplify to get 6.5*5 which then equates to 32.5.
Answer:
First, you need to know how to multiply two monomials together. A monomial is a one term polynomial.
2x × 5x, 2x²y × 3xy², and ab² × 4b³ are examples of products of monomials.
To multiply monomials together, multiply the number parts together and multiply the variables together.
Here are the 3 examples above solved:
2x × 5x = 10x²
2x²y × 3xy² = 6x³y³
ab² × 4b³ = 4ab^5
To multiply two polynomials together, multiply every term of the first polynomial by every term of the second polynomial. then combine like terms.
Example:
(2x² + 3x - 8)(4x³ - 5x²) =
= 2x² × 4x³ + 2x² × (-5x²) + 3x × 4x³ + 3x × (-5x²) - 8 × 4x³ - 8 × (-5x²)
= 8x^5 - 10x^4 + 12x^4 - 15x³ - 32x³ + 40x²
= 8x^5 + 2x^4 - 47x³ + 40x²
This is a lot of material in very little space. You need to start with simple examples of multiplication of 2 monomials. Then practice multiplying a monomial by a binomial. Then practice with polynomials of more terms.
The annual interest would be $24 since 120=5 years, 120 divided by 5 equals 24
