(b). Find the sides of the smallest square?

Answers
Step-by-step explanation:
[tex]\large\underline{\sf{Solution-}}[/tex]
Given that,
ABCD is a square of side x cmEFGH is a square of side y cmFurther given that,
Sum of all sides = 52 cmIt means
Perimeter of square ABCD + Perimeter of square EFGH is 52 cmWe know,
[tex] \purple{\rm :\longmapsto\:\boxed{\tt{ Perimeter_{[square]} \: = \: 4 \times side \: }}}[/tex]
So, using this, we have
[tex]\rm :\longmapsto\:4x + 4y = 52[/tex]
[tex]\rm :\longmapsto\:4(x + y) = 52[/tex]
[tex]\rm\implies \:\boxed{\tt{ x + y = 13}} - - - - (1)[/tex]
Now, Further given that,
If square EFGH is cutting out from square ABCD, the area of remaining part is 91 square cm.
It means
[tex]\rm :\longmapsto\:Area_{[ABCD]} - Area_{[EFGH]} = 91[/tex]
We know,
[tex] \purple{\rm :\longmapsto\:\boxed{\tt{ Area_{[square]} = 4 \times side}}}[/tex]
So, using this, we get
[tex]\rm :\longmapsto\: {x}^{2} - {y}^{2} = 91[/tex]
can be further rewritten as using algebraic Identity,
[tex]\rm :\longmapsto\:(x + y)(x - y) = 91[/tex]
[tex]\rm :\longmapsto\:13(x - y) = 91[/tex]
[tex]\red{ \bigg\{ \sf \: \because \: using \: equation \: (1) \bigg\}}[/tex]
[tex]\rm\implies \:\boxed{\tt{ x - y = 7}} - - - - (2)[/tex]
On adding equation (1) and (2), we get
[tex]\rm :\longmapsto\:2x = 13 + 7[/tex]
[tex]\rm :\longmapsto\:2x = 20[/tex]
[tex]\rm\implies \:\boxed{ \: \bf \: \: x \: = \: 10 \:cm \: \: }[/tex]
On substituting the value of x in equation (1), we have
[tex]\rm :\longmapsto\:10 + y = 13[/tex]
[tex]\rm :\longmapsto\:y = 13 - 10[/tex]
[tex]\rm\implies \:\boxed{ \: \bf \: \: y \: = \: 3 \:cm \: \: }[/tex]
So,
[tex]\rm\implies \:\boxed{Side_{[square \: EFGH]} = y \: = 3 \: cm}[/tex]
and
[tex]\rm\implies \:\boxed{Side_{[square \: ABCD]} = x \: = 10 \: cm}[/tex]
Also,
[tex]\rm :\longmapsto\:\boxed{Area_{[square \: ABCD]} = {10}^{2} = 100 \: {cm}^{2} }[/tex]
[tex]\rm :\longmapsto\:\boxed{Area_{[squareEFGH] }\: = {3}^{2} = 9 \: {cm}^{2} }[/tex]

Answer:
y = -3/4(x -2)
Step-by-step explanation:
You are given point (2, 0) on the new pipeline. To find the equation of it, you need to know the slope of the line on the graph. A careful look at the graph shows you the line goes through grid points that are separated by 4 units horizontally, and 3 units vertically. For a positive horizontal change, the vertical change is negative, so the slope is ...
m = rise/run = -3/4
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
For m = -3/4 and (h, k) = (2, 0), the equation is ...
y = -3/4(x -2)
_____
Additional comments
If you use the distributive property to eliminate parentheses, the equation becomes ...
y = -3/4x +3/2
The slope of the red pipeline can also be determined by considering the slope of the blue pipeline. The two marked points on that line have a horizontal separation of 3 and a vertical separation of 4. Its slope is ...
m = rise/run = 4/3
The slope of the perpendicular (red) line is the opposite reciprocal of this:
-1/m = -1/(4/3) = -3/4 . . . . as we determined from the red line's graph

Good luck!
Answer:
12 miles on 2 gallons of gasoline
Step-by-step explanation:
First, we need to find the unit rate and that can simply be found by dividing.
So we divide 42 miles by 7 gallons which equal 6.
So we know for every One gallon there is 6 miles. So we simply multiply 6 and 2 and we get an answer of 12 miles.
So therefore the answer is a boat can travel 12 miles on 2 gallons of gasoline.
solve. 2x−4+2x=−6x−2
Answers
Answer:
x = 1/5
Step-by-step explanation:
2x − 4 + 2x = −6x −2
Combine the like terms (2x)
Result:
4 − 4 = − 6 − 2
Add 4 to both sides:
4 − 4 + 4 = − 6 − 2 + 4
Result:
4 = − 6 + 2
Add 6x to both sides.
4 + 6 = − 6 + 2 + 6
Result:
1 0 = 2
Divide both sides by 10:
1 0 / 1 0 = 2/ 1 0
Result:
x = 1/5
Therefore, x = 1/5 would be your answer.

find the value of k so that the two given lines are parallel. -5x+kx=4 2y-9x=11
Answers
The value of k so that the two given lines are parallel is; k = 22.5
First, the correct question is;
-5y+ kx = 4 and 2y-9x=11In line segment geometry;
The slopes of two or more parallel lines are equalFirst, we must determine the slope of the lines by rewriting the equations to resemble the equation of a line in the slope-intercept form; y = mx + c
Therefore, we have;
y = (k/5)x - 4/5.................eqn(1)and y = (9/2)x + 11/2....,........eqn(2)Evidently, the slope of the line in equation 2 is; 9/2.
And since the slope of parallel lines are equal;
k/5 = 9/2By cross product;
2k = 45k = 22.5

PLS MARK BRAINLIEST
Answer:
x = 54
Step-by-step explanation:
If the lines are treated as parallel , then
(3x - 27) and (2x + 27) are alternate exterior angles and congruent, so
3x - 27 = 2x + 27 ( subtract 2x from both sides )
x - 27 = 27 ( add 27 to both sides )
x = 54

What is the solution to the equation −p−13=−43p+23(5p−6)?
Answers
Answer:
p = 125/73
Step-by-step explanation:
−p − 13 = −43p + 23 (5p − 6)
−p − 13 = −43p + 115p − 138
−p − 13 = 72p − 138
+p +p
-----------------------------
-13 = 73p - 138
+138 +138
-----------------------------
125 = 73p
/73 /73
-----------------------------
125/73 = p
If you need the answer in mixed fraction, then it's --> p = 1 52/73
The solution to the given equation is p = - 1.71
To determine the solution of the given equation,
We will find the value of the variable, p, that satisfies the equation.
From the question, the given equation is
[tex]-p-13 = -43p+23(5p-6)[/tex]
To solve this,
First, Clear the brackets
[tex]-p-13 = -43p + 115p - 138[/tex]
Now, Collect like terms
[tex]-p +43p -115p = -138 + 13[/tex]
[tex]73p = -125[/tex]
Now, divide both sides of the equation by 73
[tex]\frac{73p}{73} = \frac{-125}{73}[/tex]
∴ p = - 1.71
Hence, the solution to the given equation is p = - 1.71
