p²-q²
p²-q²= (p+q)(p-q)
[by formula: (A+B)(A-B) = A²-B²]
Proof of the formula
Proof of the formula (A+B) • (A-B)
Proof of the formula (A+B) • (A-B) = A2 - AB + BA - B2
Proof of the formula (A+B) • (A-B) = A2 - AB + BA - B2 = A2 - AB + AB - B2
Proof of the formula (A+B) • (A-B) = A2 - AB + BA - B2 = A2 - AB + AB - B2 = A2 - B2

someone please please answer this I really need help
Answer:
We have ordered pairs (60,360), (120,720), (180,1080), (240,1440), and (300,1800) as the answer.
Step-by-step explanation:
The table would look like this:
Under minutes you would place 60, 120, 180, 240, and 300.
Under calories you would place 360, 720, 1080, 1440, and 1800.
y = 6x
Multiply 60, 120, 180, 240, and 300 by 6 for 6 calories. This gives us the ordered pairs above.

Find the slope of the line passing through (1,3) and (0, -3)
Answer:
Step-by-step explanation:
Slope is y2 - y1 / x2 - x1
x1= 1
x2= 0
y1=3
y2=-3
(-3-3) / (0-1) = -6/-1 = 6

Identify the missing parts in the proof.
Given: ∠ABC is a right angle.
DB bisects ∠ABC.
Prove: m∠CBD = 45°
A:
B:
C:
D:
Answer:
The missing parts of the proof includes;
1) ∠ABC = m∠CBD + m∠ABD = 90° (Angle addition postulate)
2) m∠CBD = m∠ABD (Definition of angle bisector)
3) m∠CBD + m∠ABD = m∠CBD + m∠CBD (Substitution property of equality)
Step-by-step explanation:
The given details of the proof are;
∠ABC is a right angle = 90°
Line DB is a bisector of ∠ABC
Therefore;
1) ∠ABC = m∠CBD + m∠ABD = 90° by angle addition postulate
By the definition of angle bisector, we have;
The angles formed by line DB from ∠ABC are equal,
2) m∠CBD = m∠ABD by the definition of angle bisector
3) m∠CBD + m∠ABD = 90° = m∠CBD + m∠CBD = 2 × m∠CBD by substitution property of equality
2 × m∠CBD = 90°
∴ m∠CBD = 90°/2 = 45°
Answer:
A: Given
B: measure the angle ABC = 90
C: angle addition postulate
D: 2 times the measure of angle CBD = 90

Yes, because the data are grouped into categories.
Yes, because the data can be displayed by a
relative frequency compared with the whole.
No, because the data do not consist of parts of a
whole.
No, because the data categories are too broad.

When we factor (7x + 6) (x + 1), we would go back to
7x² + 13x + 6
---------------------------------------------------------------------------------------------------------------
Have a great summer :)
Answer:
(7x+ 6 ) (x + 1 )
Step-by-step explanation:
7x^2 + 13x+6
This factors into
(7x+ ) (x + )
They give us 6 in the first term We know that the constant is 6 we need a 1 to make the constant to be 6
6*1 = 6
(7x+ 6 ) (x + 1 )
Circle T is shown. Line PS and line RS are tangent to circle T. What is the measure, in degrees, of angle PTR
0Answer:
Angle PTR is 136*
Step-by-step explanation:
In Question, We Have Given
Line PS and RS are Two Tangent To Circle With Centre T & ∠PSR=44* .
Thus ∠SPT=90* & ∠SRT=90* (Property Of Tangent ↔ Tangent always Form 90* With Radius Of Circle)
Now We Have A Quadrilateral SPTR & The Sum Of All Angle Of Quadrilateral is 360* .
Thus The Angle Of PTR is
∠PTR = 360* - ( 90*+90*+44*)
∠PTR = 360* - 224*
∠PTR = 136*
