Answer:

422 Square Inches

Step-by-step explanation:

6x7=42

7x13=91

6x13=78

(2)42+(2)91+(2)78=422

You are multiplying each calculation by 2 because a rectangular prism has 6 sides. 2 sides height x width, 2 sides height x length, and 2 sides width x length

Tell whether the following equations are true or false. Then, explain your reasoning.
lorasvet [3.4K]

Answer and explanation:

Given : Equations

1) x + 6g-6g = x

2) 2f-4e + 4e = 2f

To find : Tell whether the following equations are true or false. Then, explain your reasoning.

Solution :

Equation means when left hand side and right hand side of the equation is same.

1) x + 6g-6g = x

Take LHS,

LHS=x + 6g-6g

Same term with opposite sign cancel each other or sum is zero,

LHS=x

LHS=RHS

Therefore, Yes, it is true as it satisfy definition of equation.

2) 2f-4e + 4e = 2f

Take LHS,

LHS=2f-4e + 4e

Same term with opposite sign cancel each other or sum is zero,

LHS=2f

LHS=RHS

Therefore, Yes, it is true as it satisfy definition of equation.

I need the answer and work plss help
OlgaM077 [116]

Answer:

B

Step-by-step explanation:

x-5+3x-5+90=180 you set it up this way because you need to find what x is equal to and by adding those two equations plus 90 then setting the against 180 you can find x because all three angles in a triagnle add up to 180.

x-5+3x-5+90=180

4x-10+90=180              you combined like numbers

4x+80=180                   combined like numbers

    -80    -80                 subtract 80 from both sides because you are trying to---                                     get x alone

4x=100                          now to get x alone you have to divide 4 from both     ----                                     sides

/4    /4

x=25                              answer
