Answer:

7) 230mm

8) 98m

Step-by-step explanation:

7)

7x+8+6x+6+9x-4 =22x+10

if x is 10 mm, 22(10)+10 =230mm

8) perimeter of rec =2( l + w )

=2 ( 2x-5+2x+6 ) = 8x + 2

if x  is 12 metres, 8(12)+2 =98m

P − 10p + -5p + 14p − -9p − 2 = -20
djverab [1.8K]

You will need to work left to right.

p - 10p + -5p +14p - -9p - 2 = -20

-9p + -5p +14p - -9p - 2 = -20

-14p +14p - -9p - 2 = -20

0p- -9p - 2 = -20

9p - 2 = -20

Then you will want to eliminate 2 by adding it to both sides

9p = -18

Then divide by 9 to isolate P

p=-2

The volume of a 10 ounce box of cheerios is 258.75in3. the length of the box is 4 inches less than the height and the width is 3
Marina86 [1]

Answer:

Height of the box = 11.5 in

Step-by-step explanation:

Let h be the height of the box.

Assuming the volume of the Box is 258.75\ in^3.

Given:

Length = Height - 4 = h - 4

Width = 3 in

We need to find the height of the box.

Solution:

We know that the volume of the box.

Volume = Length\times height\times width

Substitute all given value in above formula.

258.75 = (h-4)\times h\times 3

Rewrite the equation as:

258.75 = 3h(h-4)

258.75 = 3h^2-12h

3h^2-12h-258.75=0

whole equation divided by 3.

h^2-4h-86.25=0

Use quadratic formula with a = 1, b = -4,c=-86.25

h=\frac{-b\pm \sqrt{(b)^{2}-4ac}}{2a}

Put these a, b and c value in above equation.

h=\frac{-(-4)\pm \sqrt{(-4)^{2}-4(1)(-86.25)}}{2(1)}

h=\frac{4\pm \sqrt{16+345}}{2}

h=\frac{4\pm \sqrt{361}}{2}

h=\frac{4\pm 19}{2}

For positive sign

h=\frac{23}{2}  

h = 11.5 in

For negative sign

h=\frac{-15}{2}

h = -7.5

We take positive value of h.

Therefore, the height of the box h = 11.5 in
