Answer:

Step-by-step explanation:

They gave you an easy triangle. You can tell by the coordinates that X and Z are horizontally aligned, and Y and Z are vertically aligned, so Z is a right angle.

Area = 0.5(XZ)(YZ) = 0.5(3)(3) = 4.5 square units.

Rewrite using a single exponent.<br> 53.53

Helga [31]

Answer:

${5}^{6} \: \: or \: \: {25}^{3} = 15625$

Step-by-step explanation:

${5}^{3} \times {5}^{3}$

Here we can solve this in 2 ways ,

Method 1 :

${5}^{3} \times {5}^{3}$

Here the bases are equal. So,

$= > {5}^{3 + 3} = {5}^{6} = 15625$

Method 2 :

${5}^{3} \times {5}^{3}$

Here the exponents are same. So,

$= > {(5 \times 5)}^{3} = {25}^{3} = 15625$

The number w and 0.8 are additive inverses.

umka2103 [35]

Since, the number w and 0.8 are additive inverses.

A number 'a' is said to have an additive inverse '-a' if "a+ (-a)= 0".

Since, 'w' and '0.8' are additive inverses of each other such that $w + 0.8 = 0$

Therefore, the value of 'w' should be '-0.8' so that $-0.8 + 0.8 = 0$ .

So, the value of 'w' is =0.8

Now, Refer to the attached image which represents the position of 0.8 , w ( that is -0.8) and the sum of 0.8 and w.

Sum of 0.8 and w = 0.8 + w

= 0.8 +(-0.8)

= 0.

2. If x=2, y=3 find<br>value of <br>x²-5y+2

Damm [24]

Answer:

-9

Step-by-step explanation:

Substitute the give values into the correct place in the equation.

Since x=2, y=3,

Place "2" in the x of the equation, and "3" into the y of the equation.

x²-5y+2

= 2² - 5(3) + 2

= 4 - 15 + 2

= -9

thomas buys a cardboard sheet that is 8 by 12 inches. let x be the side lenghth of each cut out. create an equation for the volu

nikitadnepr [17]

Hi there!

Lets dive into the problem, starting with the equation for volume; length x width x height.

If it's 8 x 12 inches, That means the height is 8 and the length is 12. The side, or width, would be x.

The equation should be 8 times 12 times x, or (8)(12)(x).
