Return to the original problem. PEMDAS says to multiply before adding. But could you have performed a different operation and still have gotten a correct answer? Which one? Explain.

(4x2 + 8x + 15) + (x2 − x − 27) − (x + 5)(x − 7)

Answer:

12 cubes

Step-by-step explanation:

If the total volume of the box is 24 cm³ and the volume of each cube is 1 cm³ then that means that 24 total cubes can fit perfectly inside the box. Since there can only be two layers of cubes then we simply need to divide the total amount of cubes that will fit in the box by 2 to find the number of cubes in each layer...

24 / 2 = 12 cubes

Finally, we can see that each layer within the box will contain 12 cubes

Answer:

The answer is $240

Step-by-step explanation:

You multiply 1.5 times 60 minutes and get 90, you then add 150 and 90 and you get 240.

Step-by-step explanation:

3x-6+x+90°=180°

4x+84=180

4x=96°

x=96/4

x=24°

Answer:

14.96 is the area of the triangle

Answer:

Step-by-step explanation:

To find the area of a quarter circle, find the area of the whole circle by using the formula A = pi * r^2 and then divide by 4. To find the perimeter of the quarter circle, find the circumference of the whole circle, divide by 4, and then add the radius twice.

Answer: [tex]\frac{\pi *r^{2} }{4}[/tex]

Step-by-step explanation:  We know that the formula for the area of a whole circle is πr². A quarter circle is one-fourth of a circle, so if we divide the area of the whole circle into four, we can find the area of the quarter circle: [tex]\frac{\pi *r^{2} }{4}[/tex]

Answer: x < 4

Step-by-step explanation: You are trying to isolate the variable, x, so you have to subtract 1 on both sides of the inequality. Then, you are left with x < 4.

Given:

The equation is

[tex]y=\log_2x[/tex]

The domain is [tex]\{\dfrac{1}2, 1, 2, 4, 8, 16\}[/tex].

To find:

The graph of six points that would satisfy the equation.

Solution:

We have,

[tex]y=\log_2x[/tex]

For [tex]x=\dfrac{1}{2}[/tex],

[tex]y=\log_2\dfrac{1}{2}[/tex]

[tex]y=\log_22^{-1}[/tex]

[tex]y=-1[/tex]                          [tex][\because \log_aa^x=x][/tex]

Similarly, at x=1,

[tex]y=\log_22^0[/tex]

[tex]y=0[/tex]

At x=2,

[tex]y=\log_22^1[/tex]

[tex]y=1[/tex]                      [tex][\because \log_aa^x=x][/tex]

At x=4,

[tex]y=\log_22^2[/tex]

[tex]y=2[/tex]                      [tex][\because \log_aa^x=x][/tex]

At x=8,

[tex]y=\log_22^3[/tex]

[tex]y=3[/tex]                      [tex][\because \log_aa^x=x][/tex]

At x=16,

[tex]y=\log_22^4[/tex]

[tex]y=4[/tex]                      [tex][\because \log_aa^x=x][/tex]

Answer:

Ishaan is now 6.

Step-by-step explanation:

If Ben is 12 years older, and you have the info that three years ago, he was 4 times as old, then all you have to do is divide 12 by 4, giving you 3. You add 3 to that because it's been three years. You have your answer of 6.

Hope this helps! :)

3/4 x 3/8 = 9/32

Step-by-step explanation:

Answer:

[tex]y = -\frac{2}{3}x + 5[/tex]

Step-by-step explanation:

First you have to find the slope

[tex]m = \frac{7 - 3}{-3 - 3} = \frac{4}{-6} = -\frac{2}{3}[/tex]

Now use the point-slope form by using one of the points and the slope.  Let's use the point (3, 3)

[tex]y - 3 = -\frac{2}{3} (x - 3)[/tex]

Multiply thru the equation by 3 to remove the fraction

3y - 9 = -2(x - 3) =

3y - 9 = -2x +6

3y = -2x + 15

[tex]y = -\frac{2}{3}x + 5[/tex] is the equation in slope-intercept form

Step-by-step explanation:

To find the total surface area of a prism, you need to calculate the area of two polygonal bases, i.e., the top face and bottom face. And then calculate the area of lateral faces connecting the bases. Add up the area of the two bases and the area of the lateral faces to get the total surface area of a prism.

Hope this helps!

All the love, Ya boi Fraser :)

Answer:

By drawing a net, you can see each face of the prism. You can find the areas of each face and then add them together to find the total surface area.

Answer:(a)

Step-by-step explanation:

A function is a relation between two sets that associates the distinctive components of the first set to the second set distinctive elements.

Points are [tex](-1,3), (2,5), (3,8), (4,5)[/tex]

given points is not a function because each point is not associated with a unique point. for example, 2 and 4 is associated with the same number 5
