Help me answer please

Mathematics
1 answer:
fiasKO [112]3 years ago
6 0

Answer:

25

Step-by-step explanation:

b=4x+1    h=x+1     A=175

A=bh

Substitute: 175=(4x+1)(x+1)

Expand: 175=4x^2+5x+1

Subtract 175

4x^2+5x-174=0

Solve w/quadratic formula

(-5 <u>+</u> sqrt(25+2784))/8

Simplify: x=6 or -29/4

Distance is positive, so x=6

4x+1=4*6+1=25

A plank of wood is 220 cm long.I cut it in 14cm pieces. what lenght of wood i will have left over?
Nana76 [90]

The required Length is 10cm.

What is length?

  • Length is a measure of distance. In the International System of Amounts, length is a volume with dimension distance. In utmost systems of dimension a base unit for length is chosen, from which all other units are deduced.
  • Length is generally understood to mean the most extended dimension of a fixed object. still, this isn't always the case and may depend on the position the object is in.
  • Varied terms for the length of a fixed object are used, and these include height, which is the perpendicular length or perpendicular extent, and range, breadth, or depth. Height is used when there's a base from which perpendicular measures can be taken. range or breadth generally relates to a shorter dimension when the length is the longest one.

220 / 14 gives us 15.

You have to understand that this means 15 whole 14 cm pieces and a Length of 1 piece.

thus 14 * 15 = 210

So 220- 210 = 10

where you know 220- 210 is< 15

Hence, The correct Length is 10cm.

Solve for c: a(c−b)=d
Sindrei [870]

Answer:

a(c-b) = d

Use the distributive property, which states: x(y-z) = xy - xz

a(c-b) = ac - ab

ac - ab = d

Add ab on both sides

ac = d + ab

Divide both sides by a to isolate c

Can anybody help me with explaining polynomials and multiplying them with exponents to please don’t give me a random answer just
zloy xaker [14]

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.
