Answer:
CPCTC - Corresponding Parts of Congruent Triangles are Congruent
Step-by-step explanation:
When two triangles are congruent, this means they have the same shape and the same size. To have the same shape, each angle must be congruent. To have the same size, each side length must be congruent. When you know two triangles are congruent you can say each corresponding part of congruent triangles is congruent. This is known as CPCTC.
Step 1- multiply 40 by 25 to get 1000
step2- multiply 8 by 5 to get 40
step3- divide 1000 by 4 to get 250
answer. 250 pieces
us pascal triangle
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
each number is the sum of 2 above it and the 1's are on the outside because only 1 number is above them and its 1
so since its ^4 we use row 4 (actually the 5th because the top row is row zero)
these at the coefficients
so here is
1a^4b^0-4a^3b^1+6a^2b^2-4a^1b^3+1a^0b^4
or easier to see it vertically
notices how exponential start a 4 and 0 until 4 goes down to 0 and 0 goes up to 4
(3x - 1)
a = 3x
b = -1
1a^4b^0 = 1(3x)^4(-1)^0
-4a^3b^1 = -4(3x)^3(-1)^1
+6a^2b^2 ....
-4a^1b^3 .....
+1a^0b^4....
then write it horizontally
I think you see now, when you expand this you will have your answer
Answer:
x = 12
Step-by-step explanation:
g(x) - × + 4 =0
put g(x) = 8
so, 8 - x + 4 = 0
x = 12
