Answer:
x=1.5$x=-3/7
Step-by-step explanation:
(2x-3)(2*2+7x-1)
(2x-3)(3+7x)
6x+14x^2-9-21x
x=1.5$x=-3/7
Answer: 6.8829172362
Explanation:
sin35=e/12
Multiply 12 on each side
12sin35=e
Divide the estimated number by the exact number and multiple by 100
Answer:
Step-by-step explanation:
a. 16b^2c^12-0.25 can be rewritten as follows because it is the difference of two squares:
(4bc^6 - .5)(4bc^6 + .5)
b. 81x^6y^2-0.36a^2
is the difference of two squares, just like (a) (above); its factors are:
(9x^3y - 0.6a)(9x^3y + 0.6a)
