Answer:

Width = 152 cm

Length = 3040 cm

Step-by-step explanation:

We are given that the length of one flat square shaped slab is 231.04 cm².

Since it is a square, dimension of one side of the flat slab = √231.04 = 15.2 cm

Since there are ten flat slabs, with of the 10 slabs = 10 × 15.2 = 152 cm

Now these slabs are placed across 200 rows to form a walkway.

Thus, length = 200 × 15.2 = 3040 cm

Make 'y' the subject of the equation. g = 3y - 9.

Vikentia [17]

Answer:

$y = \frac{g+9}{3}$

Step-by-step explanation:

g = 3y -9

start by adding 9 to each side:

g + 9 = 3y

now divide by 3 on each side to get y alone:

$y = \frac{g+9}{3}$

hope this helps!

Which of the following expressions are factors of p(x)=60x4+24x3−45x2−18x?

Whitepunk [10]

The factors are 3x, 4x^2-3 and 5x+2

So, Option B, C and F are correct.

Step-by-step explanation:

We need to find factors of the expression $p(x)=60x^4+24x^3-45x^2-18x$

Solving the expression: $p(x)=60x^4+24x^3-45x^2-18x$

Taking 3x common:

$p(x)=3x(20x^3+8x^2-15x-6)$

Now, factor by grouping, the terms inside the bracket.

$p(x)=3x((20x^3+8x^2)+(-15x-6))$

$p(x)=3x(4x^2(5x+2)-3(5x+2))$

$p(x)=3x(4x^2-3)(5x+2)$

So, the factors are 3x, 4x^2-3 and 5x+2

So, Option B, C and F are correct.

5|2x - 3| + 4 = 9 How do you solve this

agasfer [191]

Answer:

x = 2, or x = -1

Step-by-step explanation:

If 2x - 3 is inside the parenthesis (), then the value of x is 2.

If 2x - 3 is inside the absolute value sign, then the value of x will probably be -1.

Solution 1

(10x-15) + 4 = 9

10x -11 = 9

10x = 20 -> x = 2

Solution 2 (Not 100% sure)

|10x -15| +4 = 9

10x + 15 +4 = 9

10x + 19 = 9

10x = -10 -> x = -1

Please correct me if I'm wrong.
