How do you use multiplication to find the perimeter of a square

Since a square has 4 equal sides, you can take the base x the height. So if your square is a 4x4, you can just multiply 4 x 4. It would be the same as adding 4+4+4+4

Which congruence criteria can be used directly from the information about triangles HIJ and MNO to prove IJ¯¯¯¯¯¯≅MN¯¯¯¯¯¯¯¯¯¯ b
skelet666 [1.2K]

Answer: \overline{IJ}\cong \overline{MN}

Step-by-step explanation:

Given: In triangle HIJ and triangle MNO we have

\overline{HI}\cong \overline{NO}, \angle{I}\cong \angle{N} ,\angle{H}\cong \angle{O}

here, HI and NN are the included side between  ∠I & ∠H and ∠N and ∠O.

So , by ASA congruence rule,

ΔHIJ ≅ ΔMNO

So by CPCTC  (corresponding parts of the congruent triangles are congruent)

\overline{IJ}\cong \overline{MN}

4x - 2y = -20<br> 7x + 2y = -2
Brut [27]

Answer:

(-2, 6)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination
  • Solving systems of equations by graphing

Step-by-step explanation:

<u>Step 1: Define systems</u>

4x - 2y = -20

7x + 2y = -2

<u>Step 2: Rewrite systems</u>

4x - 2y = -20

  1. Add 2y to both sides:                    4x = 2y - 20
  2. Divide 4 on both sides:                 x = 1/2y - 5

<u>Step 3: Redefine systems</u>

x = 1/2y - 5

7x + 2y = -2

<u>Step 4: Solve for </u><em><u>y</u></em>

<em>Substitution</em>

  1. Substitute in <em>x</em>:                         7(1/2y - 5) + 2y = =-2
  2. Distribute 7:                              7/2y - 35 + 2y = -2
  3. Combine like terms:                11/2y - 35 = -2
  4. Add 35 to both sides:              11/2y = 33
  5. Isolate <em>y</em>:                                   y = 6

<u>Step 5: Solve for </u><em><u>x</u></em>

  1. Define original equation:                    7x + 2y = -2
  2. Substitute in <em>y</em>:                                     7x + 2(6) = -2
  3. Multiply:                                                7x + 12 = -2
  4. Subtract 12 on both sides:                   7x = -14
  5. Divide 7 on both sides:                        x = -2

<u>Step 6: Graph systems</u>

<em>Check the system.</em>

Miguel’s team won the game. What is the negation of this statement?
Pavel [41]

Answer:

answer: "Miguel's team did not win the game".

Step-by-step explanation:

Negation of a statement means if a statement is true then it's negation is false and if a statement is false then it's negation is true.

Here, we are given a true statement "Miguel's team won the game" so it's negation will be a false statement "Miguel's team did not win the game".

Solve the following system using substitution. Remember to record your answer as (x, y).
natta225 [31]

Answer:

You already have what you are going to substitute, just put the y values from the first equation into the second! Like this:

6x - 5(-2x - 9) = -19

Multiply it out:

6x +10x +45 = -19

Add like terms + simplify:

16x + 45 = -19

16x = -64

x = -4

take that x and put it back into the first equation!!

y = -2(-4) -9

y= 8-9

y= -1

so... your answer is (-4, -1)

hope this helps!
