Hi,

1 m² = 100 cm times 100 cm = 10,000 cm²

If there are 23 grass plants in 100 cm², then an entire m² contains:

23\cdot\dfrac{10,000\;cm^2}{100\;cm^2}=23\cdot 100=2,300\;grass\;plants.

-424 +122-72+2
Xelga [282]

Answer:

The expression "-424 +122-72+2" doesn't seem to have anything to do with the rest of the problem.  The sum of what was written is -372.  There are no unknowns (x's) in this expression, and yet the work shows x's in the analysis.

Step-by-step explanation:

What does "by using

202+1

polynomial long division."  mean??

do the numbers after the x's represent exponents?

e.g.:  "2x + 1) - 4x4 + 12x3 - 7x + 2" is really "2x + 1) - 4x4 + 12x^3 - 7x + 2"

A circle is inscribed in a square. The area of the circle is 507 square inches. What is the length of each side of the square? U
Lena [83]

Answer:

26 inches

Step-by-step explanation:

We are given;

  • An inscribed circle whose area is 407 square inches
  • In this case, we need to know that an inscribed in a square touches the four sides of the triangle.
  • Therefore, the diameter of the circle is equivalent to the side of the square.

We are given the area as 507 square inches

But;

Area of the circle = pi × r²

Thus we can get the radius of the circle;

Thus;

507 in² = 3 × r²

r² = (507 ÷ 3)

   = 169

r =√169

  = 13 inches

But, Diameter = 2 r

Thus; Diameter = 2 × 13

                        = 26 inches

But, in this case, diameter = side of the square

Therefore, the side of the square is 26 inches

Write out the steps that you would follow to solve the equation: 3(x-4) = 2x +5
luda_lava [24]

Answer:

x = 17

Step-by-step explanation:

To solve this equation, we can illustrate the algebraic concepts being employed and solve for the variable.

3(x - 4) = 2x + 5 Distribute the 3 into the parentheses.

3x - 12 = 2x + 5 Subtract 2x from both sides of the equation to combine like terms.

x - 12 = 5 Add 12 to both sides of the equation.

x = 17
