12. The perimeter of a rectangle is 50 feet. The width is 5 less than the
length. What are the dimensions of the rectangle? (Write your answer as
Length, Width)
Answers
Step-by-step explanation:
Length = x
Width = (x-5)
Perimeter = 2 lengths + 2 widths
50 ft = x + x + (x-5) + (x-5)
50 ft = 4x - 10
60 ft = 4x
15 ft = x
length = x = 15 ft
width = (x-5) = (15 -5) = 10 ft
dimensions = length × width
= 15 ft × 10 ft
if you wanna check,
50 ft = x + x + (x-5) + (x-5)
50 ft = 15 + 15 + (15-5) + (15-5)
50 ft = 30 +(10+10)
50 ft = 30 + 20
50 ft = 50

Is ∆GAS ≅ △_____
By rule____
Answers
Answer:
ΔGAS ≅ ΔIOL By the Angle-Angle-Side (AAS) rule of congruency
Step-by-step explanation:
The given information are;
Statement [tex]{}[/tex] Reason
Segment [tex]\overline {SA}[/tex] is congruent to [tex]\overline {OL}[/tex] [tex]{}[/tex]As shown in the diagram provided
∠SAG is congruent to ∠LOI [tex]{}[/tex] As shown in the diagram provided
∠SGA is congruent to ∠LIO [tex]{}[/tex] As shown in the diagram provided
Therefore, ΔGAS ≅ ΔIOL By the Angle-Angle-Side (AAS) rule of congruency
Given that the the number of interior angles of triangle = 3 and the sum of the interior angles of a triangle = 180°, the third angle can be defined by specifying the measure of two of the angles
Therefore, the Angle-Angle (AA) rule of similarity can be used to prove the congruency of two triangles when they have one side of each triangle which are congruent.
Answer:
∆GAS ≅ △IOL By rule ASA, AAS
Step-by-step explanation:
By looking at the triangle, you can see two little quarter-circle things inside the triangle (I don't know what they are called). That means it has 2 angles. We already know that it can't be SSS or SAS because we have 2 angles, as I said.
If you look at the triangle's sides, you can see that there is a side with a dash on it. That means that it is a side in ASA, AAS, etc. So there we go. We've figured it out. There is one side and two angles. Therefore, our answer is ASA or AAS

On Monday, Jayla raised $30 and Carlos raised $50.
After that, Jayla raised $12 per day and Carlos
raised $7 per day. After how many days will they
have raised the same amount?
They will raise the same amount after days.
Answers
Answer:
84 days
Step-by-step explanation:
You would use the LCM to solve this.
12 and 7 don't share any common factors other than 1,
so you would multiply 12 x 7, which gets you 84.
After 84 days they would have raised the same amount.

Sue wants to put a rectangular garden on her property using 88 meters of fencing. There is a river that runs through her property so she decides to increase the size of the garden by using the river as one side of the rectangle. (Fencing is then needed only on the other three sides.) Let x represent the length of the side of the rectangle along the river. Express the garden's area as a function of x. what is the largest area that can be enclosed?
Answers
Answer:
Area = 44x - x²/2
Step-by-step explanation:
Given that:
Meter of fencing = 88m
Length of side of rectangle along the river = x
Only one more length is needed since river as been used as one side length of the fence.
Length = x
Width of rectangle = y = 2y (for both sides)
Hence ;
x + 2y = 88 meters
Expressing in terms of y
2y = 88 - x
y = (88 - x) / 2
y = 44 - x/2
Area of rectangle = Length * width
Area = x * y
Area = x * (44 - x/2)
Area = 44x - x²/2
Maximum. Area :
Perimeter = 4s
88 = 4s
s = 88/4 = 22
x = 2(22) = 44 = Length ; y = 22 = width
Maximum area = (22 * 44) = 968m²

Answer:

Step-by-step explanation:
-95= 14x - 7 + 30x (collect like terms)
-95 = 44x - 7 (add 7 on each side)
-88 = 44x (divide by 44 on each side)
-2 = x
-95= 14x+23
-23= 14x

Wow! There are 2 things going on here, so let's go step by step.
The first thing to notice is that the numbers are going negative, positive, negative, positive. Odd-numbered terms are negative while even-numbered terms are positive. Since 9 is odd number, we know the answer must be negative.
Secondly, the 1, 4, 9, 16 sequence is called the square numbers. They are 1 x 1, 2 x 2, 3 x 3, 4 x 4, etc. The 9th term will be 9 x 9 ( ignoring the negative).
Adding the first point with the second, we get (-81) { negative eighty-one }
