Taya2010 [7]

Answer:

4

Step-by-step explanation:

ΔABC is congruent with ΔDEF.  That means the corresponding sides are congruent.

Look at the order of the letters.  EF are the last two letters of ΔDEF.  So this corresponds with the last two letters of ΔABC.  Therefore, EF ≅ BC.

EF ≅ BC

x² + 8x = 48

x² + 8x − 48 = 0

(x + 12) (x − 4) = 0

x = -12 or 4

Since x can't be negative, x = 4.

X^2-15x+54 can someone help me factor it
deff fn [24]
X^2 -15x +54 = 0 for you can factor it easy just you need getting two numbers with sum equal -15 and product equal 54 

-15= (-9)+(-6) and (-9)*(-6)= -54 in this way will get 

x^2 -15x +54 = (x-6)(x-9)

hope helped

Which of these equations, when solved, gives a different value of x than the other three? 9.1 = -0.2x + 10 10 = 9.1 + 0.2x 10 –
garik1379 [7]

Given:

Different equations are given.

Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining.

To find:

The equation which gives a different value of x than the other three.

To find the equations that could you use to find the price of one tire patch.

Solution:

In option A,

9.1 = -0.2x + 10

0.2x= 10-9.1

0.2x= 0.9

Divide both sides by 0.2.

x=\dfrac{0.9}{0.2}

x=4.5

Similarly,

In option B,

10 = 9.1 + 0.2x

0.9= 0.2x

4.5=x

In option C,

10-0.2x = 9.1

-0.2x = -0.9

x = 4.5

In option D,

9.1 – 10 = 0.2x

-0.9 = 0.2x

-4.5 = x

Since option D has difference solution, therefore the correct option is D.

Let price of one tire patch be x.

So, price of 4 tire patches = 4x

Remaining amount in Rhyan's gift card = $1.90

Total amount = $22.20

Price of 4 tire patches + Remaining amount in gift card = Total amount

4x+1.9=22.2

It can be written as

4x-22.2=-1.9,1.9=22.2-4x,22.2-4x=1.9

Therefore, the correct options are C and E.

I need help on this question I’m confused
AysviL [449]

Answer:

FG = 31

Step-by-step explanation:

By applying mid-segment theorem in the given trapezoid,

Segment joining midpoints of the nonparallel sides is parallel and measure the half of the sum of parallel sides.

FG = \frac{1}{2}[UV+TW]

(7x - 4) = \frac{1}{2}[(6x-6)+38]

2(7x - 4) = 6x + 32

14x - 8 = 6x + 32

14x - 6x = 32 + 8

8x = 40

x = 5

Therefore, FG = (7x - 4)

                        = 7(5) - 4

                        = 31
