Answer:
Talia is not correct. The lateral area has three faces, so the expression should be 3 (one-half (8) (6.9)).
Step-by-step explanation:
A triangular prism has four triangles, three at the sides and one at the base.
A congruent shape has the same feature (side dimensions and angles), therefore all three sides of the prism, and the basal triangle have the same area (since they are congruent).
The area of the base will be One-half (8) (6.9), therefore each of the three sides too will have that same area.
Lateral area means only the areas of the sides excluding the base, therefore, the lateral area will be 3 (one-half (8) (6.9))

Answer:
[tex]x= \frac{-23}{5}, y=\frac{-1}{5}[/tex]
Step-by-step explanation:
3x + y = -14
-2x + y = 9
We'll try to find x
(-2x + y = 9) multiplied by -1 => -1(-2x+y=9) = 2x-y = -9
3x + y = -14
+2x -y = -9
+__________
3x + 2x +y -y = -14 - 9
5x = -23
x = -23/5
3x + y = -14 =>And now we can find y. Just plug in -23/5 for x
[tex]3\frac{-23}{5} + y = -14[/tex]
[tex]\frac{-69}{5} + \frac{5y}{5} = \frac{-70}{5}[/tex]
[tex]\frac{5y}{5} =\frac{-1}{5}[/tex]
5y = -1
y = -1/5

Here is a pattern made from sticks:
//////
//////////
////////////// How many sticks would be in pattern number 6?
b)
How many sticks would be in pattern number n?
Answer:
a) 26 sticks
b) an = 6 +4(n -1)
Step-by-step explanation:
You have patterns of sticks that have 6 sticks in the first pattern, 10 sticks in the second pattern, 14 sticks in the third pattern, and you want to know the number of sticks in the 6th pattern and in pattern number n.
b) Arithmetic sequenceYou have a sequence of patterns with 6, 10, and 14 sticks. The first pattern has 6, and the following patterns each have 4 more than the one previous. The sequence of numbers is an arithmetic sequence with a first term a1=6, and a common difference d=4.
The n-th term of such a sequence is given by the formula ...
an = a1 +d(n -1)
For the first term and common difference in this sequence, the number of sticks in pattern n is ...
an = 6 +4(n -1)
a) Sixth patternWhen n=6, the number of sticks is ...
a6 = 6 +4(6 -1) = 26
There would be 26 sticks in pattern 6.

The perimeter of a rectangular field is 342 m. If the width of the field is 76 m, what is it’s length?
Answer:
The length is 95 m
Step-by-step explanation:
P = 2(l+w) where l is the length and w is the width
342 = 2(l+76)
Divide each side by 2
342/2 = 2/2(l+76)
171= l+76
Subtract 76 from each side
171- 76 = l+76-76
95 = l

¿Cuántos litros de agua se precisa para llenar una piscina inflable de 1/4 de metro cúbico?
Answer:
250 litters
Step-by-step explanation:
To solve this question, we first need to know the conversion from cubic meter to liter.
1 cubic meter is equal to 1000 liters.
So, if we have 1/4 cubic meter, we can use a rule of three to find how many liters we will need:
1 m3 -> 1000 L
1/4 m3 -> x L
x * 1 = (1/4) * 1000
x = 1000 / 4 = 250 L
So we need 250 liters of water.

Whats the product of (-3x+2y)(4x-y)
Answer:
-12x^2 + 11xy - 2y^2
Step-by-step explanation:
Answer:
-12x² + 11xy - 2y²
Step-by-step explanation:
To solve this:
You can distribute -3x to 4x
-3x*4x = -12x²
Then distribute the -3x to -y
-3x*-y = 3xy
Distribute the 2y to 4x
2y*4x = 8xy
Distribute the 2y to -y
2y*-y = -2y²
-12x² + 3xy + 8xy - 2y²
Combine like terms and add 3xy to 8xy
Final Answer: -12x² + 3xy + 11xy - 2y²

Which step is the same in the construction of parallel lines and the construction of a perpendicular line through a point on the line?
Answer:
D.Place the compass on a point on the original line.
Complete Question:
A.Create only one arc that intersects the original line.
B.Create two arcs that intersect the original line.
C.Place the compass on a point off the original line.
D.Place the compass on a point on the original line.
Step-by-step explanation:
* Lets revise the steps of constructing parallel lines and a perpendicular line through a point on the line
# Contracting parallel lines
- Given: Line AB and point P not on AB
1. Draw a slant line through point P and intersects AB at point C, this line is the transversal of the parallel lines
2. Place the pin of the compass at point C and draw an arc intersects AB at D and CP at E
3. Without changing the distance of the compass put the pin of the compass on point P and draw an arc intersects CP at point Q
4. Use the compass to measure the distance from D to E and place the pin of the compass at point Q and draw an arc intersects the arc from P to CP at point U
5. Join P and U by a line this line is parallel to AB
# Constructing a perpendicular line through a point on the line
- Given line AB and point P lies on it
1. Place your compass pin at P and draw an arc of any size below AB that crosses the line twice at points C and D
2. Stretch the compass to a larger distance
3. Place the compass pin on point C and draw a small arc above the line
4. Without changing the distance of the compass place the compass pin on point D and draw another arc intersects the arc from C at point E
5. Using a straightedge, join P and E where PE is perpendicular to AB
* Lets find the same steps in the constructions
∵ In first construction we put the pin of the compass at point C which lies in the original line AB
∵ In second construction we put the pin of the compass at point P which lies in the original line AB
∴ The common step is: "Place the compass on a point on the original line"
Answer:
just know the answer is not Create only one arc that intersects the original line.

Step-by-step explanation:
Answer:
My Question was The slope of the line shown between the points (-7, -3) and (-4, 0) is equal to its slope between the points (0, 4) and (6, 10).
Which of the following best describes triangle TUV and triangle XYZ?
answer: Triangle TUV is similar to triangle XYZ.
Step-by-step explanation:
Point V is at (-7, -3), and point T is at (-4, 0). So, the slope of the line between (-7, -3) and (-4, 0) is equal to the ratio of UT to VU.
Point Z is at (0, 4), and point X is at (6, 10). So, the slope of the line between (0, 4) and (6, 10) is equal to the ratio of YX to ZY.
Since the slope between (-7, -3) and (-4, 0) is equal to the slope between (0, 4) and (6, 10), the ratio of UT to VU is equal to the ratio of YX to ZY.
Two right triangles are similar if the ratios of two sets of their corresponding sides are congruent. Therefore, triangle TUV is similar to triangle XYZ.
