Answer:
Step-by-step explanation:
JK + KL = JL
x² - 4x +3x - 2 = 28
x² - x - 2 = 28
x² - x -2 - 28 = 0
x² - x - 30 = 0
Sum = -1
Product = -30
Factors = -6 , 5 {-6 + 5 = -1 and (-6)*5 = -30}
x² + 5x - 6x - 30 = 0 {Rewrite the middle term}
x(x + 5) - 6(x + 5) = 0
(x + 5)(x - 6)= 0
x -6 = 0 {X +5 = 0 is ignored as measurement will not be negative}
x = 6
JK = x² - 4x
= 6² - 4*6
= 36 - 24
JK = 12
KL = 3x -2
= 3*6 - 2
= 18 - 2
KL = 16

Answer:
1. 10 6/7 2. 8/15
Step-by-step explanation:
1. 6 1/42 + 4 5/6
First, let's combine the whole numbers. 6 + 4 = 10Now we are left with 1/42 + 5/6.To add or subtract, the dominators need to be the same. We need to find the least common multiple which here is 42.1/42 + 5/6(7)
1/42 + 35/42
= 36/42
= 6/7
All we have to do is combine both numbers.10 6/7
2. 13/15 - 1/3(5)
13/15 - 5/15

A quart floor has a side length of 7x^5y^6 units. A square tile has a side length of x^2y units. How many tiles will it take to take to cover the floor?
About 49 tiles will be needed to cover the floor
A square is a shape having equal sides. The area of a square is expressed as:
A = L²
L is the side length of a square.
If a square tile has a side length of x²y units, the area of the square tile will be:
A = (x²y)²
As = x⁴y² units²
Similarly, if a quart floor has a side length of 7x⁵y⁶ units. The area of the quart floor will be expressed as:
Aq = (7x⁵y⁶)²
Aq = 49x¹⁰y¹²
Divide both areas to get the number of tiles that will cover the floor
Number of tiles = 49x¹⁰y¹²/x⁴y²
Number of tiles = 49x⁶y¹⁰
This shows that about 49 tiles will be needed to cover the floor.

The denominator of a rational number is greater than its numerator by 7. If the numerator is increased by 6 and the denominator is decreased by 5, the new rational number obtained is 3/2. Find the original rational number.
Answer:
6/13
Step-by-step explanation:
6 + 6 = 12 3
---- ---- = ---
13 - 5 = 8 2
Answer:
Original Rational number is = 6/13Step-by-step explanation:
Let Numerator be : x
Denominator be : x + 7
Now,
Numerator is increased by 6Denominator is decreased by 5the new rational number obtained is 3/2Numerator = x + 6
Denominator = ( x + 7) - 5
According to the question,
[tex] \displaystyle \: \sf \dashrightarrow \: \frac{x + 6}{(x + 7) \: - 5} = \: \frac{3}{2} [/tex]
[tex]\displaystyle \: \sf \dashrightarrow \: 2(x + 6) \: = 3 \{ \: (x + 7 ) - 5\} \: [/tex]
[tex]\displaystyle \: \sf \dashrightarrow \: 2x \: + 12 \: = \: 3(x + 2)[/tex]
[tex]\displaystyle \: \sf \dashrightarrow2x + 12 \: = 3x + 6[/tex]

Denominator = x + 7

A regular square-based pyramid has a surface area of 33 m2. If its triangular faces have an area of 6 m2, what is the length of the base of the pyramid?
Answer:
First we can do 33 time 6
Step-by-step explanation:
The length of the base of the pyramid is 3 meters.
What is a square pyramid?A pyramid is a polyhedron that has a base and 3 or greater triangular faces that meet at a point above the base. A square pyramid is a pyramid with a square base, four triangular sides, five vertices, and eight edges.
For the given situation,
The surface area of the pyramid = 33 m^2
Area of triangular faces = 6 m^2
Let the base of the pyramid be b and the height be h.
The formula of area of triangle is
[tex]A = \frac{1}{2}(b)(h)[/tex]
⇒ [tex]6 = \frac{1}{2}(b)(h)[/tex]
⇒ [tex]6(2) = (b)(h)[/tex]
⇒ [tex]12 = (b)(h)[/tex]
The formula of surface area of square pyramid is
[tex]SA = b^{2}+2bh[/tex]
⇒ [tex]33=b^{2} +2(12)[/tex]
⇒ [tex]33-24=b^{2}[/tex]
⇒ [tex]b=\sqrt{9}[/tex]
⇒ [tex]b=3[/tex]
Hence we can conclude that the length of the base of the pyramid is 3 meters.

PLEASE PLEASE PLEASE HELP TRANSLATING SENTENCES INTO EQUATIONS
Answer:
5×(w + 7) = 4
Step-by-step explanation:
w is the unknown number.
5 times something means multiply something 5 times.
a sum means adding things
so, the sum of a number and 7 is
w + 7
5 times that sum is then
5×(w + 7)
and that while thing is (equals) 4
5×(w + 7) = 4
by the way, solving that means
5w + 35 = 4
5w = -31
w = -31/5
Answer:
5(w + 7) = 4
Step-by-step explanation:
Do one part of the sentence at a time until you write the entire sentence as an equation.
"Five times the sum of a number and 7 is 4."
The problem tells us to use w for the number, so we write w below.
w
"Five times the sum of a number and 7 is 4."
Now we move on to the part dealing with the sum of the number and 7. A sum is an addition, so we add 7 to the number w.
w + 7
"Five times the sum of a number and 7 is 4."
Now we take care of the part dealing with product of 5 and the sum.
5(w + 7)
"Five times the sum of a number and 7 is 4."
The last part is dealing with the part "is 4". The word "is" very often means "equals", so the entire expression we wrote is equal to 4.
5(w + 7) = 4
Answer: 5(w + 7) = 4

Answer:
22801
Step-by-step explanation:
#40
No. of terms = (301 + 1)/2
No. of terms = 302/2
No. of terms = 151
Now,
Sum = n²
Sum = (151)²
Sum = 22801
Answer:
For #40.
S = 22801
Step-by-step explanation:
On #40 the last term is 301, so we add 1
[tex]302[/tex] ÷ [tex]2 = 151[/tex]
[tex]n = 151[/tex]
To get [tex]n^{2}[/tex], multiply 151 by itself
[tex]151[/tex] × [tex]151 = 22801[/tex]
[tex]S = 22801[/tex]
