Rewrite the expression -2a(a+b-5)+3(-5a+2b)+b(6a+b-8)

Nimfa-mama [501]

First separately:
$-2a(a+b-5) = -2a^{2}-2ab+10a$
$3(-5a+2b) = -15a + 6b$
$b(6a+b+8) = 6ab+b^{2}+8b$

Then you add then all together and get:
$-2a^{2}-2ab+10a-15a + 6b+ 6ab+b^{2}+8b =$
$-2a^{2}-5a+4ab+14b+b^{2}$

(02.03 MC) The temperature at a mountain base camp was −2 degrees Celsius on Thursday. Friday morning, the temperature was 1 deg

aev [14]

Answer:

The temperature at the base camp Friday evening is - 6 degrees Celsius.

Step-by-step explanation:

To get the temperature at a mountain base camp on Friday evening, we must translate statement into a mathematical form:

(i) The temperature at a moutain base camp was - 2 degress Celsius on Thursday:

$T_{o} = -2\,^{\circ}C$

(ii) Friday morning, the temperature was 1 degree Celsius lower than it was on Thursday:

$\Delta T_{1} = -1\,^{\circ}C$

(iii) Friday evening, the temperature was 3 degrees Celsius lower that it was that morning:

$\Delta T_{2} = -3\,^{\circ}C$

The temperature at the base camp Friday evening is:

$T = T_{o}+\Delta T_{1}+\Delta T_{2}$

$T = -2\,^{\circ}C-1\,^{\circ}C-3\,^{\circ}C$

$T = -6\,^{\circ}C$

The temperature at the base camp Friday evening is - 6 degrees Celsius.

A right angle triangle has sides whose lengths are $2$-digit integers. The digits of the length of the hypotenuse are the revers

Kazeer [188]

Answer:

Smallest possible length of the hypotenuse = 65

Step-by-step explanation:

Given - A right angle triangle has sides whose lengths are $2$-digit integers. The digits of the length of the hypotenuse are the reverse of the digits of the length of one of the other sides.

To find - Determine the smallest possible length of the hypotenuse.

Proof -

The possible Pythagoras triplets of a right angled triangle with 2 digit integers are -

(11, 60, 61)

(12, 35, 34)

(13, 84, 85)

(16, 63, 65)

(20, 21, 29)

(28, 45, 53)

(33, 56, 65)

( 36, 77, 85)

(39, 80, 89)

(48, 55, 73)

(65, 72, 97)

But, Here Given that

The digits of the length of the hypotenuse are the reverse of the digits of the length of one of the other sides.

So, There is only one possibility that satisfy the condition.

and that is, (33, 56, 65)

So, we get

Length of one side = 33

Length of second side = 56

Length of hypotenuse = 65

So,

Smallest possible length of the hypotenuse = 65
