Answer:
132 inches squared
Step-by-step explanation:
Area is 132 inches squared
Method 1:
Area of parallelogram = base x height = 11inches x 12 inches = 132 inches squared
Method 2:
Move the triangle divided by the dotted line on the right to the left.
It becomes a rectangle of 11 inches by 12 inches. 11 inches x 12 inches = 132 inches squared.

5|x +9| < 10
x< ?
x> ?
Answer:
x<−7 and x>−11
Step-by-step explanation:
Let's solve your inequality step-by-step.
5(|x+9|)<10
Step 1: Divide both sides by 5.
5(|x+9|)/5 < 10/5
|x+9|<2
Step 2: Solve Absolute Value.
|x+9|<2
We know x+9<2 and x+9>−2
x+9<2(Condition 1)
x+9−9<2−9(Subtract 9 from both sides)
x<−7
x+9>−2(Condition 2)
x+9−9>−2−9(Subtract 9 from both sides)
x>−11
Answer:
x<−7 and x>−11

Mark has 580 stamps. Debbie has 720 stamps than Mark. How many stamps must Debbie give to mark so that Mark have 120 more than she?
480 stamps must be given to Mark
Answer: 130 stamps.
Step-by-step explanation:
Let amount оf the stamps Debbie must give to Mark so that Mark have 120 more than she is x.
Hence,
(580+x)-(720-x)=120
580+x-720+x=120
2x-140=120
2x=260
2*x=2*130
x=130.
So, 130 stamps Debbie must give to Mark so that Mark have 120 more than she.

Solve for X. HELP?!
Answer:
x = 90
Step-by-step explanation:
In this figure the exterior angle is 130°
An exterior angle is the sum of the interior angles. The interior angles are x and 40 so x + 40 = 130 giving x = 130-40 = 90
Answer:
∠ x = 90°
(90 degrees)
Step-by-step explanation:
When two angles combine to make a straight line, we know that their angle values must add up to 180
Here, we can see that 130 combines with an inner angle to form a straight line. (I will be calling this interior angle z )
So, 130 + z = 180
130 + z = 180
- 130 -130
z = 50
We also know that all angles in a triangle must add up to 180 degrees, and because we know the two other angles of our triangle now, we can find x
z + x + 40 = 180
50 + x + 40 = 180
90 + x = 180
- 90 -90
x = 90
So, the measure of angle x is 90°

area of sector - area of white Δ
area of sector = area of circle × fraction of circle
