What is (2x + 1)(3x + 7) simplified
2 answers:
Answer:
+17x+7 and zeros are -7/3 and -1/2
Step-by-step explanation:
You multiply every property by every variable not in their own parentheses.
2x*3x=6x^2
2x*7=14x
3x*1=3x
7*1=7
6x^2+3x+14x+7
add like variables together 3x+14x
6x^2+17x+7
( To get the zeros just make each equation in the parentheses equal to zero and solve for x.) ex 2x+1=0 x=-1/2

Answer:
Step-by-step explanation:
The fractions above are known as mixed numbers (that is, fractions that contain the combination of a whole number and proper fraction). The mixed numbers can equally be renamed as improper fractions. However, renaming can only occur the the mixed numbers are being transformed as below:
The transformation occur through a simple approach thus: for the first mixed number; 2 1/3 = 2 multiplied by 3 plus 1 divide by 3 equals 7/3. Similarly, mixed number 1 3/4 is transformed by this: 1 multiplied by 4 plus 3 divide by 4 equals 7/4.
Simplifying further to arrive at final result implies,
Take the LCM of the denominators (4 × 3 =12) and simplify thus:
