(x + a) (x + b) = x² + (a + b) x + ab
75 * 77=
=(70+5)(70+7)
=70²+(5+7)*70+5*7
=4900+12*70+35
=4900+840+35
=5775

Answer:
20.1246118 or 20.12
Step-by-step explanation:
First draw the box with the diagonal, as you can see it is split into 2 equal right triangles. Now use the pythagorean theorem (a^2+b^2=c^2) to find the length of the diagonal
A . 1/15 equals 0.66
b. 5/12 equals 0.4166
c. 1/3 equals 0.333
d. 5/12 equals 4.6 as a round number
8). 0.4 equals 4/10 equals 2/5
9) 7.32 equals 7 3/2
10) 0.2 equals 2/10 equals 1/5
Hope this helps:)
