Choose the best estimate for the multiplication problem below. 56 x 51 A. 2000
B. 3000
C. 4100​

If a =6, what is the value of 2a(3b + 5c)?

Which linear equations have an infinite number of solutions? check all that apply.  (x  –  3/7)  =  2/7(3/2x  –  9/14)8(x  +  2)  =  5x  –  1412.3x  –  18  =  3(–6  +  4.1x)(6x  +  10)  =  7(x  –  2)4.2x  –  3.5  =  2.1 (5x  +  8)

Ineed with angles and the measure of them i have abc a is 65 and b is (3x-10) and c is (2x) find the value of x
