Select all equations that are equivalent to (5x+6)2=3−(4x+12) .
a. 5x+6=3−(4x+12)
b. (5x+6)2=−4x−9
c. 52x+3=3−(4x+12)
d. (5x+6)2=−4x+15
e. 5x+6=−8x−18
Answers
Answer:
B
Step-by-step explanation:
ita only b .............
The equations that are equivalent to (5x + 6)2 = 3-(4x +12) is (5x+6)2=−4x−9.
Option B is correct.
The very first thing to do is to solve the expression in the given question.
SO,
(5x + 6)2 = 3-(4x +12)
Open brackets
10x + 12 = 3 - 4x - 1210x + 12 = -4x - 9Collect like terms
10x + 4x = -9 - 1214x = -21x = -21/14
Now, we will solve each of the given options to determine which one corresponds to the solution to the expression above.
Starting with Option (a)
5x + 6 = 3 - (4x + 12)
Open brackets
5x + 6 = 3 - 4x - 125x + 6 = -4x - 95x + 4x = -9 - 69x = -15x = -15/9Option (a) is incorrect
b.
(5x + 6 )2 = -4x - 9
Open brackets
10x + 12 = -4x -9Collect like terms10x + 4x = -12 -914x = -21x = -21/14Option (b) is correct
(c.)
52x + 3 = 3 - (4x + 12)
Open brackets
52x + 3 = 3 - 4x - 1252x + 3 = -4x - 952x + 4x = -9 - 356x = - 12x = -12/56x = -3/14Option (c) is incorrect
(d)
(5x + 6)2 = -4x + 15
Open brackets
10x + 12 = -4x + 1510x + 4x = -12 + 1514x = 3x = 3/14Option (d) is incorrect
(e)
5x + 6 = -8x - 18
Collect like terms
5x + 8x = -18 - 613x = - 24x = -24/13Option (e) is incorrect
Therefore, we can conclude that the correct equation equivalent to the given expression in the question can be seen in Option b.

If a point (x,y) is rotated 90 degrees counterclockwise around the origin, what will the resulting coordinate be?
Answers
Answer:
Step-by-step explanation:
90 degrees clockwise will result in a (+,+) answer.
90 degrees counterclockwise will result in a (-,+) answer.
Think of your quadrants.
Quadrant 1 the answer will be (+,+)
Quadrant 2 the answer will be (-,+)
Quadrant 3 the answer will be (-,-)
Quadrant 4 the answer will be (+,-)
It all depends where you are starting, so if you have to go counter clockwise from the third quadrant, your answer will be a coordinate that is (+,-).

Pour tout réel x, on pose : f(x) = -2x²+4x+6. Vérifier que (-1) est une racine de ce polynôme f. On sait que l'axe de symétrie de la parabole qui représente f est la droite d'équation : x=1. Déduire de cette information l'autre racine du polynôme f. Factoriser le polynôme f. Aidez-moi svp meci d'avance
Answers
Explication étape par étape:
Étant donné la fonction polynomiale f (x) = -2x² + 4x + 6. Pour vérifier si f (-1) est un facteur de l'expression, nous devons montrer que f (-1) est équivalent à zéro. S'il est nul, donc x + 1 est un facteur du polynôme.
Preuve
f (x) = -2x² + 4x + 6
f (-1) = -2 (-1) ² + 4 (-1) +6
f (-1) = -2 (1) -4 + 6
f (-1) = -2-4 + 6
f (-1) = -6 + 6
f (-1) = 0
Puisque f (-1) = 0, donc x + 1 est un facteur du polynôme.
Ensuite, il faut obtenir l'autre racine du polynôme. Pour obtenir cela, nous devons factoriser la fonction polynomiale donnée.
Soit f (x) = 0
-2x² + 4x + 6 = 0
multiplier par -1
2x²-4x-6 = 0
diviser par 2
x²-2x-3 = 0
x²-3x + x-3 = 0
x (x-3) +1 (x-3) = 0
(x + 1) (x-3) = 0
x + 1 = 0 et x-3 = 0
x = 1 et x = 3
Par conséquent, l'autre racine du polynôme en dehors de 1 est x = 3

digital piano is 54 inches. Will it fit along the
wall next to the bookshelf? Explain your answer.
please help!!
explain good and clearly:) I’ll give you brainliest!!
Answers
*see attachment for the drawing
Answer:
No. The width is longer than the space available along the wall next to the bookshelf.
Step-by-step explanation:
The scale of the length of the space the piano is to occupy along the wall close to the bookshelf = 12 cm - 4 cm = 8 cm
Actual length of the space given a scale of 1 cm to 6 in: 6*8 = 48 in
The piano is said to have a width of 54 inches, therefore, it will not fit along the wall next to the bookshelf. The space available along the bookshelf is just only 48 inches long, which is less than the width of the piano.
Answer:
No
Step-by-step explanation:
It does not fit

I REALLY NEED HELPPPPP!! Write a paragraph proof for the following conjecture:
Given: m∠ 1 + m∠ 2 = m∠ 4
Prove: m∠3 + m∠1 + m∠2 = 180
Answers
Answer:
Given: measure 1 + measure 2 = measure 4
measure 4 + measure 3 must be 180 degrees because they are supplementary
If measure 4 + measure 3 is 180, and measure 1 + measure 2 = measure 4, we can substitute measure 4 in the first equation for measure 1 + measure 2.
Therefore, we arrive at the answer measure 1 + measure 2 + measure 3 = 180.

What’s the value of X?
Answers
Answer:
x = -2
Step-by-step explanation:
Step 1: Write equation
2(x - 6) + 6 = 4x - 2
Step 2: Solve for x
Distribute 2: 2x - 12 + 6 = 4x - 2Combine like terms: 2x - 6 = 4x - 2Subtract 2x on both sides: -6 = 2x - 2Add 2 to both sides: -4 = 2xDivide both sides by 2: -2 = xRewrite: x = -2Step 3: Check
Plug in x to verify it's a solution.
2(-2 - 6) + 6 = 4(-2) - 2
2(-8) + 6 = -8 - 2
-16 + 6 = -10
-10 = -10
Answer:
distribute the 2. add -12+6. add 2 to both sides. decide both sides by 2. x= -2
A father is 30 years elder than his son. after 8 years he will be 4 times as old as his son. find their present ages
Answers
Father is 30 years older than the son.
After 8 years , he will be 4 times as old as his son.
Find:their present ages
Solution:Let the son's age be x and age of father be y years
⟹ Father's age = Son's age + 30
⟹ y = x + 30 -- equation (1)
Also,
Son's age after 8 years = (x + 8) years.
Father's age after 8 years = (y + 8) years.
According to the above condition,
⟹ y + 8 = 4(x + 8)
⟹ y + 8 = 4x + 32
Substitute the value of y from equation (1).
⟹ x + 30 + 8 - 32 = 4x
⟹ 6 = 4x - x
⟹ 6 = 3x
⟹ 6/3 = x
⟹ 2 = x
Substitute the value x in equation (1).
⟹ y = 2 + 30
⟹ y = 32
Therefore,
Son's present age = x = 2 years.
Father's present age = y = 30 years.
I hope it will help you.
Regards.
Answer:
→ 11(2 + y) + 11y
→ 22 + 11y + 11y = 154
→ 22y + 22 = 154
→ 22y = 154 - 22
→ 22y = 132
→ y = 132/22
→ y = 6
