Answer:

f(x) = -x^2 -6x - 1

Step-by-step explanation:

Answer:

y=-x^2-6x-1

Step-by-step explanation:

f(x)=-(x+3)^2+8

f(x)=-(x+3)(x+3)+8

f(x)=-(x^2+3x+3x+9)+8

f(x)=-x^2-3x-3x-9+8

f(x)=-x^2-6x-9+8

f(x)=-x^2-6x-1

y=-x^2-6x-1

Answer:

Thea answer is below

Step-by-step explanation:

A triangular prism is a polyhedron (a three dimensional shape) made of a triangular base and 3 faces joining corresponding sides.

The triangular prim has 5 faces of which two are triangular and three are rectangular. It also has 6 vertices and 9 edges.

The lateral surface area of a triangular prism = (a + b + c)h; where a, b and c are the sides of the triangular base and h is the height of the triangle.

Given that a = b = c = 6 cm, h = 15 cm. Hence:

Lateral surface area = (6 + 6 + 6)15 = 270 cm²

Answer:

B) 8x - 20 + 2x = 11

Step-by-step explanation:

4(2x - 5) + 2x = 11

use pemdas

parenthesis comes first

open the parenthesis

4 * 2x - 4 * 5 + 2x = 11

8x - 20 + 2x = 11

The property of 30°-60°-90° :

The side opposite the 30° angle is the shortest and the length of it is equal to half of the length of the hypotinuse.

Answer:

Rhombus

Step-by-step explanation:

This undoubtedly has to be a rhombus. When you look at other quadrilaterals for example and want to judge and or differentiate, we see that in the case of a square, the diagonals are equal to one another and they are not congruent. Same can be applied to that of a rectangle as well, it's diagonals aren't congruent, even if they appear perpendicular.

On the other hand, the diagonals of a rhombus is both perpendicular, and at the same time congruent. And thus, that's our answer

3/5

first we find gcf for both numinator and dinominator do the gcf is 15

next we divide both by15

then 45÷15=3 and 75 ÷15=5

so the answer is 3/5 or 3:5

Answer:

D) 125x²¹- 64y³  

Step-by-step explanation:

A) x⁶ + 27y⁹ = (x²)³ + (3y³)³  - sum of cubes

B) 3x⁹ - 64y³ - the first term is not a cube

C) 27x¹⁵ - 9y³ - the second term is not a cube

D) 125x²¹- 64y³ = (5x⁷)³ - (4y)³ - difference of cubes

Correct option is the last one

Answer:

86

Step-by-step explanation:

2 + 2 = 4

4 cubed is 64

150 - 64 = 86

Have a great day <3

Answer:

86

Step-by-step explanation:

[tex]150 - (2 + x)^{3}[/tex]

x = 2

[tex]150 - (2 + 2)^{3}[/tex]

BEDMAS

(brackets)

⇒ [tex]150 - (2 + 2)^{3}[/tex]

⇒ 150 - [tex]4^{3}[/tex]

(exponents)

⇒ 150 - [tex]4^{3}[/tex]

⇒ 150 - 64

(subtraction)

⇒ 150 - 64

⇒ 86

Step-by-step explanation:

parallelogram

If a quadrilateral is a rhombus, then it is a parallelogram. If a parallelogram is a rhombus, then its diagonals are perpendicular. If a parallelogram is a rhombus, then each diagonal bisects a pair of opposite angles.

Answer:

angles 5,6 are supplementary

angles 7 and 4 are vertical angles

(one solution of many)

Step-by-step explanation:

Lets start with supplementary angles. those are two angles that add up to 180 degrees or make a straight angle. Two angles that fulfill this statement are 5 and 6 because 5 and 6 make a straight angle.

Now lets do vertical angles. Vertical angles are angles that are opposite of each. They are made by intersecting diagonals. One pair of angles that fulfill this are angles 7 and 4. if you can tell, they are opposite of each other.

supplementary= 5 and 6

vertical= 7 and 4

have a wonderful day!
