In a parallelogram, one angle is 9 times the size of another. Find the measures of the angles.

In a parallelogram, opposite angles are congruent. However, the same thing cannot be said for the other.

You can label one pair of opposite angles with x and the other 9x. 

You also know that each quadrilateral has interior angles that add up to 360 so you can create the equation of
9x+9x+x+x=360
which can be simplified into 

20x=360

x=18 

Now, you know the angle measures of one pair of opposite angles. to find the other you plug in 18 to our other equation and multiply 9 to get 162. 

The angles of the parallelogram is 18,18, 162 and 162. 

Note: you can check if this is right if all the angles add up to 360.

The last one is the answer.

If the number is no less than 6, that means that it is not any smaller than 6.

That narrows the answer down to x > 6 and x >= 6. The difference between these two choices is that x>6 means that x cannot equal 6, while the last choice is greater than OR equal to 6.

Since we are looking for when the minimum value for x is 6, x >= 6 is the answer.

Ymorist [56]
First, make it easy for yourself by putting like terms together
-7x+8x+5>3
then, combine like terms
-7x+8x=1x
now you have this
1x+5>3

Victor is going to send some flowers to his wife. Dayton Florist charges $3 per rose, plus $12 for the vase. Tammy's Flowers, in
s344n2d4d5 [400]

Answer: the costs would be the same if he orders 29 rose flowers.

Step-by-step explanation:

Let x represent the number of roses that Victor would order such that the cost will be the same with either flower shop.

Dayton Florist charges $3 per rose, plus $12 for the vase. This means that if he orders x rose flowers, the total amount that he would pay is

3x + 12

Tammy's Flowers, in contrast, charges $2 per rose and $41 for the vase. This means that if he orders x rose flowers, the total amount that he would pay is 2x + 41

For the costs to be the same, the number of rose flowers that he orders would be

3x + 12 = 2x + 41

3x - 2x = 41 - 12

x = 29

Need the answer to this problem
GaryK [48]
First you can solve the triangle. complete the triangle my making the final side which would equal 12 because the top and bottom are bith 6. and the bottom is 12 then you do 1/2(12)(12) to find the area which would be 72. the area of the rectangle would be 18 so the total would be 90ft^2 when you add them together

Find all the points if any where y-4x=12 intersects 2-y=2(x+2)^2
Stells [14]

Answer:

B

Step-by-step explanation:

given the 2 equations

y - 4x = 12 → (1)

2 - y = 2(x + 2)² → (2)

rearrange (1) expressing y in terms of x

y = 12 + 4x

Simplify (2) by expanding factor and substituting y = 12 + 4x

2 - (12 + 4x) = 2(x² + 4x + 4)

2 - 12 - 4x = 2x² + 8x + 8

- 10 - 4x = 2x² + 8x + 8 ← rearrange into standard form

add 10  + 4x to both sides

2x² + 12x + 18 = 0 ← in standard form

divide through by 2

x² + 6x + 9 = 0

(x + 3)(x + 3) = 0 ⇒ (x + 3)² = 0 ⇒ x = - 3

Point of intersection = (- 3, 0 ) → B
