Helppp Plzzzzzzz I Need Some Help

Answers

Answer 1

Step-by-step explanation:

x² + 8x + 15

(x²+5x)+(3x+15)

x(x+5) + 3(x+5)

(x+3) (x+5)

You can notify me if you don't understand

Answer 2

Answer:

x-ints: (-5,0) and (-3,0)

Factors: (x+5)(x+3)

Step-by-step explanation:

First, make the equation equal 0. Then, because x² is x × x, factor it by doing a diamond, so you're seeing what times 15 equals 8, so 3 times 5. The factors would be (x+5)(x+3).

Then, to get the x-ints, put that back into the equation: (x+5)(x+3)=0.

-5 + 5=0   and    -3 + 3=0, so x=-5 and -3, so the x-ints are (-5,0) and (-3,0)

9(2n + 1)

Distribute 9 to the terms in the brackets.

18n + 9

Add = 0 to solve for x

18n + 9 = 0

Move 9 to the other side by subtracting

18n = -9

Divide by 18 on both sides

n = -9/18

Simplify

n = -1/2

In decimal form the answer can also be -0.5 depending on your question.

A module house is made by sticking a triangular prism on top of a rectangular block, as shown in the diagram.

Answers

Answer:

d

Step-by-step explanation:

The volume of the triangular prism.

= Base area x length of the prism

The volume of the rectangular block.

= Length x width x height

The volume of the model house is 1260 cubic feet.

Option A is the correct answer.

What is a rectangle?

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

Module house:

Triangular prism on top and a rectangular block.

The volume of the triangular prism.

= Base area x length of the prism

= (1/2 x 12 x 4) x 15

= 24 x 15

= 360 cubic feet

The volume of the rectangular block.

= Length x width x height

= 12 x 15 x 5

= 900 cubic feet

The volume of the block house.

= Volume of the triangular prism + Volume of the rectangular block

= 360 + 900

= 1260 cubic feet

Thus,

The volume of the model house is 1260 cubic feet.

Option A is the correct answer.

Which equation could be used to solve for the length of side c, given a = 5, b = 12, and C = 72°?

Answers

Answer:

i had this question before

Step-by-step explanation:

c^2=a^2+b^2-2abcos(c)

c=sqrt(a^2+b^2-2abcos(c))

c=sqrt((5)^2+(12)^2-2(5)(12)cos(72))

c=sqrt(25+144-120cos(72))

c=sqrt(169-120cos(72))

c=sqrt(169-37.08)

c=sqrt(131.92)

c=11.49
