Answer:

If you need to simplify this equation, you will get 2x-2, if you are solving for the value of x, your answer will be x=6

Step-by-step explanation:

always work through your equations following the order of operations.

The first thing you will do is the multiplication of 3 and (x+4):

3 x (x+4)= 3x+12

once you have multiplied the 3 into the brackets, your equation will be:

5x-(3x+12)

Your next step will be to remove the brackets by carrying the subtraction sign over to each of the terms in the brackets, you will then have the equation:

5x-3x-12

Group your like terms (so simplify the 5x-3x) to get:

2x-12

This is the last step if the question is only asking you to simplify the expression, if you are solving for the variable then you will move one of the terms to the opposite side of the equals sign and will get:

2x=12 (since to swap the side you add 12 to both sides which cancels out the -12)

Simplify the expression by dividing both sides by 2 and you will be left with:

x=6

HELPPPPPPPPPPP PLZZZZZZZZZZZZZZZZZZZZ!!!!!!!!!!!!

Answer:

x = 3

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

10x + 2 is an exterior angle of the triangle, thus

10x + 2 = 2x + 1 + 25

10x + 2 = 2x + 26 ( subtract 2x from both sides )

8x + 2 = 26 ( subtract 2 from both sides )

8x = 24 ( divide both sides by 8 )

x = 3

Find the maxmium area of a rectangular plot of land which can be enclosed by rope of length 60 metres​
mario62 [17]

Answer:

225 m²

Step-by-step explanation:

If W is the width of the rectangle, and L is the length, then:

60 = 2W + 2L

A = WL

Use the first equation to solve for one of the variables:

30 = W + L

L = 30 − W

Substitute into the second equation:

A = W (30 − W)

A = 30W − W²

This is a parabola, so we can find the vertex using the formula x = -b/(2a).

W = -30 / (2 × -1)

W = 15

Or, we can use calculus:

dA/dW = 30 − 2W

0 = 30 − 2W

W = 15

Solving for L:

L = 30 − W

L = 15

So the maximum area is:

A = WL

A = (15)(15)

A = 225

Can somebody please help answer this word problem using grass method? And showing how u get the answer thanks!!!
xxTIMURxx [149]

Answer:3/20

Step-by-step explanation:

Fraction of total area mowed = (3/5) + (1/4) = 17/20

Therefore fraction of total area left = 1 - (17/20) = (20/20) - (17/20) = 3/20
