Answer:
In the first one answer is r²
In second one answer is 3
Step-by-step explanation:
Yes it is Algebra with different powers
In first one (6r4+4r) +(__- 2r4 + 3r) = 4r4 + r2 + 7r
Like terms are added:
6r^4- 2r^4 + 4r + 3r +____ = 4r^4 + r2+ 7r
4r^4+7r +___ = 4r^4 + r^2 + 7r
Therefore ___ = r^2
In second one:
(__ -8x - x^2)-(4x^2 -7 +6x) = -5x^2 +14x +10
Open the brackets
__ -8x - x^2-4x^2 +7 -6x = -5x^2 +14x +10
Add like terms
__ -14x -5x^2 + 7= -5x^2 +14x +10
Therefore
___ + 7 = 10
___ = 10 -7 = 3

Un parallélépipède rectangle posé sur une de ses faces carrées a un volume de 252cm cube, il a une hauteur de 7. Quelle est la longueur du coté de la base carré
Answers
Répondre:
6 cm
Explication étape par étape:
Volume du parallélépipède rectangle V = l²h
l est la longueur du carré basé
h est la hauteur
Étant donné
V = 252 cm³
h = 7 cm
Remplacer
252 = l² (7)
252 = 7l²
l² = 252/7
l² = 36
l = √36
l = 6 cm
D'où la longueur du côté de la base carrée est de 6 cm

Answers
Answer:
(m + 2)
Step-by-step explanation:
First, factorise out m from the first equation:
m² + 2m = m (m + 2)
Second, use difference of two squares to factorise the 2nd equation:
m² - 4 = (m + 2) (m - 2)
Third, just factorise the last one normally as you would to solve for m:
m² + 3m + 2 = (m + 2) (m + 1)
Finally, to find the lowest common multiple, you need to identify what value goes into all of the equations and that is (m + 2).

Applying the angle of intersecting tangents theorem, m∠ABC = 99°
What is the Angle of Intersecting Tangents Theorem?If two tangents intersect and form an angle outside a circle, based on the angle of intersecting tangents theorem, the angle formed equals half the positive difference of the intercepted arcs.
Given the following:
m(AD) = (17x + 2)m(AC) = (7x – 10)m∠ABC = (4x + 15),Apply the angle of intersecting tangents theorem:
m∠ABC = 1/2[m(AD) - m(AC)]
Substitute
4x + 15 = 1/2[(17x + 2) - (7x - 10)]
2(4x + 15) = 17x + 2 - 7x + 10
8x + 30 = 10x - 12
8x - 10x = -30 - 12
-2x = -42
x = -42/-2
x = 21
m∠ABC = (4x + 15)
Plug in the value of x
m∠ABC = 4(21) + 15 = 99°

A rectangle is divided into equal squares. One row covers 1/8 of the whole rectangle. There are 3 squares in each row. How many squares are in the whole rectangle?
Answers
Answer:
There are 24 squares in the entire rectangle
Step-by-step explanation:
Trom the problem, we are given that one row covers 1/8 of the entire rectangle.
We are also told that this one row, contains three squares.
In other words, what this means is that three squares cover 1/8 of the entire rectangle.
The question is now if three squares cover only 1/8 of the rectangle, how many squares cover the whole rectangle.
In fraction, we can represent a whole using 1/1
We can set up a simple relation to this effect.
3 squares give 1/8 of the rectangle
x squares give 1/1 of the rectangle
cross multiplying, we have
x = 3 ÷(1/8) = 24
Therefore, there are 24 squares in the entire rectangle
Carla wants the total weight of the bags to be four pounds. If she can only pick one more bag, which bag weight should she pick? pound
Answers
Answer:
1/8
Step-by-step explanation:
To find which bag weight Carla needs, the first step is to find the total weight of the bags shown in the line plot.
There are three -pound bags.
There are six -pound bags.
There are four -pound bags.
Multiply the weight and number of each bag to find the total weight of each different weight bag.
Now, add the three totals.
Finally, subtract the total weight from four pounds in order to find which weight Carla needs.
So, Carla should pick one -pound bag of candy to total four pounds.

From the question we are told that:
Arc [tex]AD =65 \textdegree[/tex]
Arc [tex]BC =45 \textdegree[/tex]
Given The angle of intersecting chords theorem
Generally the equation for angle BEC is mathematically given by
[tex]\angle BEC=\frac{1}{2} (\angle of arc AD+\angle of arc BC)[/tex]
[tex]\angle BEC=\frac{1}{2} (65 \textdegree+45 \textdegree)[/tex]

Determine whether the pair of coordinate pairs will make the linear inequality true or false.(10, 6).Y ≤ -5/5x+3
Answers
Answer:
False.
Step-by-step explanation:
We have the ordered pair (10, 6) and we want to see if this ordered pair is a solution of the inequality:
y ≤ -5/5x+3
Remember that a generic ordered pair is written as (x, y)
Then for the ordered pair (10, 6) we have:
x = 10
y = 6
So we just need to replace these two values in the inequality and see if the inequality is true or false.
Replacing these values we get:
6 ≤ (-5/5*10) + 3
6 ≤ (-1/10) + 3
This is false, 6 is not less than the thing at the right, so we can conclude that (10, 6) is not a solution of the inequality.
So the coordinate pair makes the inequality false.

Mr. McGill is solving the following problem: 42x=163. Mr. McGill set 2x=3 and got x=32 as his answer. Tell the mistake Mr. McGill made and tell the correct answer.
Answers
Answer:
The mistake McGill made was to eliminate 4 and 16 from both sides before solving fro x
Step-by-step explanation:
Given the expression
42x = 163
To get the values of x, we are to divide both sides by the coefficient of x i.e 42 as shown;
42x = 163
42x/42 = 163/42
x = 163/42
x = 3.88
Hence the mistake McGill made was to eliminate 4 and 16 from both sides before solving fro x
