9 + 2 = 11

9 - 11 = (-2)

Can someone help me please
Dafna1 [17]

Answer:

none

Explanation:

Fill in each option for x individually.

I)     9 \leq -10 - 4(-1)  

II)    9 \leq -10 - 4(-3)  

III)   9 \leq -10 - 4(-2)

Then, simplify the right side of each inequality.

I)    9 \leq -6

II)   9 \leq 2

III)  9 \leq -2

Each of these inequalities are flase. 9 is not less than or equal to any of these values, so the answer is none.

What is the area?? Please help
Olegator [25]

Answer:

<h3>324 ft²</h3>

Step-by-step explanation:

We have the triangle and the rectangle.

The formula of an area of a triangle:

A_{\triangle}=\dfrac{1}{2}bh

b - base

h - height

The formula of an area of a rectangle:

A_{\boxed{\ }}=lw

l - length

w - width

We have b = 24 ft, h = 7 ft, l = 24 ft and w = 10 ft.

Substitute:

A_\triangle=\dfrac{1}{2}(24)(7)=(12)(7)=84\ ft^2

A_{\boxed{\ }}=(24)(10)=240\ ft^2

The area of the figure:

A=A_{\triangle}+A_{\boxed{\ }}

Substitute:

A=84+240=324\ ft^2

∠LMN and ∠NMO are a linear pair of angles. If ∠LMN = 4x + 3 and ∠NMO = 10x – 5, then find the value of x. (1 point)
andriy [413]
Linear angles are two angles that are part of a straight angle (180*), so both must add up to 180.   If 4x+3+10x-5+180, then 14x-2=180, then 14x=182, and x=13
