4 7/12 + 2 1/12 what is the estimate answer

Pani-rosa [81]

$4 \frac{7}{12} = \frac{12*4+7}{12} = \frac{55}{12} \\ \\ 2 \frac{1}{12} = \frac{2*12+1}{12} = \frac{25}{12} \\ \\ \frac{55}{12} + \frac{25}{12} = \frac{80}{12} \\ \\ \frac{80 :4}{4:4} = \frac{20}{3}$

The map of a walking trail is drawn on a coordinate grid with three points of interest. The trail starts at R(−2, 4) and goes to

Bogdan [553]

Length from R(-2, 4) to S(3, 4) is sqrt((3 - (-2))^2 + (4 - 4)^2) = sqrt(5)^2 = 5 units

Length from S(3, 4) to T(3, -1) is sqrt((3 - 3)^2 + (-1 - 4)^2) = sqrt(-5)^2 = 5 units

Therefore, total length = 5 + 5 = 10 units.

5 points<br> Write the polynomial 5x + 2x3 + 8x2<br> 7 in standard form.

artcher [175]

Find the GCF, then factor it out. Finally, simplify each term in the parentheses.

5x + 2x3 + 8x2

$x(\frac{5x}{x}+\frac{2x^3}{x}+\frac{8x^2}{x} )$

$x(5+2x^2+8x)$
