Answer:

Question #3: Answer = 31

Step-by-step explanation

• Plug in 3 for x

• Plug in -4 for y

| -3(3)² + 2(-4) | -(3)(-4)

From here, simplify. Don't forget to use PEMDAS!

| -27 +8 | + 12

| -19 | + 12

19 + 12

31

Use this same method to solve for Question #2!

Find the measure of ∠P
Elenna [48]
To find the third angle of a triangle you can remember that ALL triangles angles add up to 180 degrees, ALWAYS

So that means that p + r + q = 180

r + q = 95

67 + 28 = 95 

So 95 + p = 180

We can subtract 95 from 180 to find what’s left so 180 - 95 = 85

The correct answer would be that the measure of angle p = 85 degrees

Because 28 + 67 + 95 = 180

I hope this helps! Dont forget to thank my answer and mark it as the brainliest if it was the most helpful! <3

ser-zykov [4K]

Answer:100B + 50M ? 25000

Step-by-step explanation: CZ 75B has a firing pin block which makes for a longer SA trigger pull. CZ 75 has the superior trigger. Aren't the magazines different (and not interchangeable) as well? IIRC, the older 75 mags are not easy to find, and can be expensive.Apr 22, 2011

Calculate the volume of the following figure.
Leni [432]

Answer:

  • \boxed{\sf{24\ units\ ^3}}

Step-by-step explanation:

In order to solve this, you must use the volume of the cube.

\underline{\textbf{VOLUME OF THE CUBE FORMULA:}}

\Longrightarrow: \sf{V=L*W*H}

  • L: (length) = 3
  • W: (width) = 2
  • H: (height) = 4

<u>Multiply.</u>

<u />

<u>Use the order of operations.</u>

<u>PEMDAS stands for:</u>

  • <u>Parentheses</u>
  • <u>Exponents</u>
  • <u>Multiply</u>
  • <u>Divide</u>
  • <u>Add</u>
  • <u>Subtract</u>

\Longrightarrow: \sf{3*2*4}

<u>First, do multiply. </u>

\Rightarrow: \sf{3*2=6}\\\\\\\Rightarrow: \sf{6*4=\boxed{\sf{24}}

  • <u>Therefore, the volume of the cube is 24 units³, which is our answer.</u>

I hope this helps. Let me know if you have any questions.
