From the figure:

m∠A = 53°+18° = 71°

m∠B = 53°+50° = 103°

m∠C = 50°+59° = 109°

m∠D = 18°+59° = 77°

Find the volume of the composite figure. please!
Irina-Kira [14]
Volume= Length * width ( aka Base ) * height 

Break up the figure into easier figures, a small square and a bigger square.

Small square- 3*2*1 = 6 cm

Large Square- 7*6*1 = 42 cm

42 + 6 = 48 cm. But wait! You have to take one more step, which is minus-ing 6 from 48. Why? Notice that there is a little area where a side of the small square meets the bigger square. That little area is worth 3 cm ( length is 3, height is 1 cm ) times 2 ( 3 cm is one side, another 3 cm is the other side from the other square ) = 6 cm.

Your total answer should be 42. ( or 48, if your teacher doesn't count the area where the squares meet/join together ).

sergejj [24]

Answer:

no

Step-by-step explanation:

if it was a factor then, 2-3x = 0

x= 2/3

putting x = 2/3 in eqn,

(2/3)^2 - 2/3 +1 =7/9....so it is not a factor

Select the set of equations that would be used to solve the following absolute value equation:|x-5|=20
-BARSIC- [3]
X-5= 20
x-5= -20

Absolute value makes a negative positive, so when you are solving x-5 could have been 20 originally or -20 originally. Solve for both.

Given x=5 + √16 , select the value(s) of x. -11 1 9 21
Schach [20]

Answer:

The answers would be 9 and 1.

Step-by-step explanation:

x= 5±√16 can be separated into two equations.

x=5+√16 and x=5-√16

1. 5+√16 can be solved by simplify √16, which is 4. So then it would become   5+4 which equals 9.

2. 5-√16 can be solved by simplifying √16 which is 4. So then it would become 5-4 which equals 1.

So the values of x are 9 and 1.

Compound Inequalities <br> (Help)
sladkih [1.3K]
- 8x + 44 ≥ 60
- 8x ≥ 60 - 44
- 8x ≥ 16
x ≤ - 2

- 4x + 50 < 58
- 4x < 58 - 50
- 4x < 8
x > - 2

Now put the two together. Logically, these two answers since a number cannot be both less than AND greater than - 2. 

Your answer should be no solution.
