Daisy looked at the table shown and claimed that for every integer value, the expression -x < x is true.

Enter an integer value that proves Daisy's claim is not true.

Answer:

Step-by-step explanation:

(a - b)² + 4ab = a² + b² - 2ab + 4ab

Combine like terms

                    = a² + b² + 2ab

                    = (a +b)²

                    = (a +b)(a + b)

Answer:

180 sq cm

Step-by-step explanation:

Square 1 formed on hypotenuse of the triangle, squares 2 and 3 are formed on the perpendicular legs of the triangle. Thus, by Pythagoras Theorem, A(square 1) will be equal to the sum of the areas of (square 2) and (square 3).

[tex]\implies A(square \:1) =A(square \:2)+A(square \:3) \\ \\ \implies \: A(square \:1) =100 + 80\\ \\ \implies \: A(square \:1) =180 \: {cm}^{2} [/tex]

Answer:

See Below

Step-by-step explanation:

[tex] \cos 240 \degree \\ = \cos (180\degree + 60\degree ) \\ = \cos 180\degree \cos60\degree - \sin 180\degree \sin60\degree \\ = ( - 1) \times \frac{1}{2} - 0 \times \frac{ \sqrt{3} }{2} \\ = - \frac{1}{2} - 0 \\ \implies \: \huge \purple{ \cos 240 \degree = - \frac{1}{2} } \\ \\ \sin 240 \degree \\ = \sin (270\degree - 30\degree ) \\ = \sin 270\degree \cos 30\degree - \cos 270\degree \sin 30\degree \\ = ( - 1) \times \frac{ \sqrt{3} }{2} - 0 \times \frac{1 }{2} \\ = - \frac{ \sqrt{3} }{2} - 0 \\ \implies \: \huge \orange{ \sin 240 \degree = - \frac{ \sqrt{3} }{2} } [/tex]

[MA]:

48 r 40

The explanation:

94 x 4 = 376

4,552 - 376 = (792 or ?)

94 x 8 = 752

792 - 752 = 40

94 is greater than 40 so we can't add anymore.

Thus, the answer is 48 r 40

Answer:

r=-2, y=-3

Step-by-step explanation:

i don't understand, what is it asking for here?

Step-by-step explanation:

correct answer is 168.

hope this helps you.

Hey there!

56 × 3

= 56 + 56 + 56

= 112 + 56

= 168

Basically you had to multiply 6(3), which gave you 18, right? Okay, so you BRING DOWN your 8 and CARRY the 1 OVER your 5. Then you MULTIPLY 5(3), which is 15, right? Then you ADD 15 + 1, which is 16,right?

Thus, that’s why: [168] is most likely your result. (Look at the picture below for better steps )

Good luck on your assignment & enjoy your day!

Step-by-step explanation:

30 feet* 1/25 = 6/5 feet = 1.2 feet

Answer:

4

Step-by-step explanation:

Hey there!

2x^2 - 5 / x + 9

= 2(-1)^2 - 5/ -1 + 9
= (2(-1)^2 - 5) / (-1 + 9)

= (2(1) - 5) / 8

= (2 - 5) / 8

= -3 / 8

≈ -0.375

Therefore, your answer is:

-3/8 OR -0.375

EITHER OF THOSE SHOULD WORK BECAUSE THEY ARE EQUIVALENT TO EACH OTHER!

Good luck on your assignment & enjoy your day!

a) The area of Australian desert is 3,830,040km²

b)The approximate number of dingos will be  517,055

a) Given the following parameters;

Area of Sahara desert = 9,000,000km²

If the Australian desert is 42.556% of the size of the Sahara desert in Africa, then the area of the Australian desert is expressed as:

Area of Australian desert = 0.42556 * 9,000,000

Area of Australian desert = 3,830,040km²

b) If dingo density is approximately 0.135 animals km² during the dry season, the approximate number of dingos in the Australian desert during this season. will be:

number of dingos =  0.135 * 3,830,040km²

number of dingos = 517,055.4

Hence the approximate number of dingos will be  517,055
