10 different pairs. Since there are 5 different brands you simply add 4+3+2+1 to get 10.
Answer:
Step-by-step explanation:
Given
See attachment for grid
Required
Find c and d
From the attachment, we have:
--- Point on A
--- Corresponding point on B
When A is reflected across the x-axis, the rule is:
So, we have:
Next, is to calculate the translation from to
This is calculated using:
and
So, we have:
---- i.e. Shift by 6 units to the left
--- i.e. Shift by 1 unit down
Answer:
I believe the answer to the first question is:
R is the midpoint of PQ. (I think)
The answer to the second question is:
Rectangle. Because rectangles are the only shape in that list that has parallel sides and congruent angles.
And the answer to the third question is:
16, 16, 18. Because an isosceles triangle is a triangle that has two sides of the same length.
I hope this helps! :)
Factor out a GCF of 4, then you are left with perfect squares.
4(100-9x^2)
Factor what is left as a difference of perfect squares (the outside and inside terms from FOIL should cancel out which is why each parenthesis has a different sign
f(10+3x)(10-3x)
Answer:
x= 3sqrt2 y=3
Step-by-step explanation:
The triangle is isosceles triangle, which means 2 sides are congruent. Therefore, y =3
using the pythagorean theorem,
3^2+3^2=x^2
9+9=x^2
18=x^2
x=18 sqrt
3sqrt2
