Answer:

surface area of cuboid=2(lb+bh+hl)

surface area of cuboid=2(7×5+5×4+4×7)

surface area of cuboid=166m²

if the shape is cuboid if it's not than tell me on comment section the figure i can help you.

OlgaM077 [116]

Answer:

see below

Step-by-step explanation:

$\frac{x-1}{x^2-3x+2}+ \frac{x-2}{x^2-5x+6} +\frac{x-5}{x^2-8x+15}$

we need to simplify that

$x^2-3x+2=(x-1)(x-2)\\\\x^2-5x+6=(x-2)(x-3)\\\\x^2-8x+15=(x-3)(x-5)$

so we can continue

$\frac{x-1}{(x-1)(x-2)}=\frac{1}{x-2}\\\\\frac{x-2}{(x-2)(x-3)} =\frac{1}{x-3}\\\\\frac{x-5}{(x-3)(x-5)} =\frac{1}{x-3}$

and we can put all together

$\frac{1}{x-2}+ \frac{1}{x-3}+ \frac{1}{x-3}\\\\\frac{1}{x-2} +\frac{2}{x-3}\\\\\frac{x-3}{(x-3)(x-2)}+ \frac{2(x-2)}{(x-2)(x-3)} \\\\\frac{x-3+2x-4}{(x-3)(x-2)}\\\\\frac{3x-7}{x^2-5x+6}$

Hajra's weekly pay this year is £676. This is 30% more than her weekly pay last year. Work out Hajra's weekly pay last year.

marissa [1.9K]

$\text{new pay}=\frac{130}{100}(\text{old pay})$ hence $\text{old pay}=\frac{130}{100}\cdot676=\boxed{\£520}$

What is the slope of the line shown below?

strojnjashka [21]

Because we're given two points on the line, we can apply the slope formula to find the answer:

$\frac{y.2 - y.1}{x.2 - x.1} = m$

-4 - 8 / 2 - (-1)

-12 / 3

-4

<h3>The slope of the line is -4.</h3>

Points showing equivalent relics on the coordinate planeten

koban [17]

Answer:

<em>Answer: (8,12) Third option</em>

Step-by-step explanation:

<u>Equivalent Ratios</u>

Nardia plotted some points showing equivalent ratios. The points shown in the graph are: (2,3), (4,6), (10,15)

The ratios of the points in the form y:x are:

$\frac{3}{2}$

$\frac{6}{4}=\frac{3}{2}$

$\frac{15}{10}=\frac{3}{2}$

Note all the ratios are equivalent.

From the ordered pairs provided in the choices, only one of them has the same ratio y:x.

Point (12,8) has a ratio:

$\frac{12}{8}=\frac{3}{2}$

Answer: (8,12) Third option
