Three times the sum of a number and seven,all divided by four

ASHA 777 [7]

Answer:

3(x+7)/4

Step-by-step explanation:

Three times the sum of a number and 7 will be 3(x+7) because it is triple the amount of that unknown number plus seven and then after that we divide what we get from 3(x+4) and divide that by 4 which makes the equation 3(x+7)/4.

Write the quadratic equation whose roots are -3 and 2 , and whose leading coefficient is 5

KiRa [710]

Step-by-step explanation:

Since, roots are - 3 & 2

Therefore, (x + 3) & (x - 2) would be factors.

Leading coefficient is 5

Hence, required quadratic equation is:

$5(x + 3)(x - 2) = 0 \\ \therefore \: 5( {x}^{2} - 2x + 3x - 6) = 0\\ \therefore \: 5( {x}^{2} + x - 6) = 0\\ \therefore \: 5 {x}^{2} + 5x - 30 = 0\: \\ is \: the \: required \: quadratic \: equation.$
