Answer:
(2x+1) (2x-7)
Step-by-step explanation:
Multiply the coefficient of the first term by the constant 4 • -7 = -28
Find two factors of -28 whose sum equals the coefficient of the middle term, which is -12
( -28 + 1 = -27
-14 + 2 = -12 )
Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -14 and 2
4x2 - 14x + 2x - 7
Add up the first 2 terms, pulling out like factors :
2x • (2x-7)
Add up the last 2 terms, pulling out common factors :
1 • (2x-7)
Add up the four terms :
(2x+1) • (2x-7)
1 US = 1.09 Australian
divide by 1.09 on both sides to find how much a 1 Australian dollar is worth.
1/1.09 = 1 Australian dollar
1 Australian dollar = 0.92 US dollar
mulitply 35 on both sides of the equation
35 Australian = 35 (0.92) = 32.2 US dollars
Answer:
When (3b³)² is simplified, it equals 3b⁶
Step-by-step explanation:
3 × 2 = 6
The exponent is 6
For the answer to the question above, to solve these questions, use this formula: X3= F(X1-X2) Y3= F(Y1-Y2)
Where X3 is the X value in the coordinate your solving for, F is the fraction,
X1 is the first X and X
2 is the second X Plug in your numbers to fit this: X3= 1/4 x (0--2) Y3= 1/4 x (4- -3) By solving you get: (-.5, 1.75)
