(i) 14×25 = 350 g fertiliser would be needed for 14 m^2 land

(ii) 450÷25 = 18 m^2 land could be fertilised with 450 g fertiliser

The lengths of the sides of the triangle are 3, 8, and 10. Is the triangle a right triangle, acute triangle, or an obtuse triang

weqwewe [10]

Answer:

Obtuse

Step-by-step explanation:

You have to make sure it is a triangle by adding the smallest and the medium sides, if the result is greater than the bigger side then it is a triangle.
you then use the Pythagorean theorem to check if the triangle is a right triangle, acute, or obtuse. If $c^{2}$ = $a^{2} +b^{2}$ then it is a right triangle. If $c^{2} >a^{2} + b^{2}$ then it is an obtuse triangle. if $c^{2} < a^{2} +b^{2}$ then it is an acute triangle.

$10^{2}$ _ $3^{2} + 8^{2}$
9+64_100
70_100
70<100

in this case $c^{2}$ is greater than $a^{2} +b^{2}$ therefore, is it an obtuse triangle.

Can I get help simplifying these three questions? Thanks!

Ludmilka [50]

1. 3a - 1 + 18 - a

So you can reorder these, as long as they keep the sign in front of them.

3a - a - 1 + 18, you can reorder it to.

And then just add or subtract.

2a + 17

2. (a+3) - (a + 2)

First you want to open the parenthesis.

To do that, check the symbol before the parenthesis.

If it's a minus, reverse the operator inside the parenthesis. If it's a plus, do nothing.

So just,

a + 3 - a - 2

Then reorder again

a - a + 3 - 2

1

3. 43 + a - 2a

Just subtract, a - 2a, to get -a.

So,

43 - a
