5. Use any method to solve the equation. If necessary, round to the nearest hundredth.

DanielleElmas [232]

Answer:

2.45, -2.45

Step-by-step explanation:

Since the equation has only one term in the unknown "x", we can solve for it isolating "x" on one side of the equal sign:

$8x^2-48=0\\8x^2=48\\x^2=\frac{48}{8} \\x^2=6\\x=+/-\sqrt{6} \\x=+/- 2.449$

Which we can round to: x = - 2.45 and x = 2.45

Find the area of the polygon.

zalisa [80]

Answer:

$A=128\ cm^2$

Step-by-step explanation:

we know that

The area of the polygon is equal to the area of a square plus the area of four congruent triangles

$A=b^2+4[\frac{1}{2}(b)(h)]$

where

$b=8\ cm\\h=4\ cm$

substitute

$A=8^2+4[\frac{1}{2}(8)(4)]$

$A=64+64=128\ cm^2$

Which is an equation in point-slope form of the line that passes through the points (4,5) and (-3,-1)?

Annette [7]

(4,5),(-3,-1)
slope = (-1 - 5) / (-3 - 4) = -6/-7 = 6/7

y - y1 = m(x - x1)
slope(m) = 6/7
using points (-3,-1)...x1 = -3 and y1 = -1
now we sub...pay attention to ur signs
y - (-1) = 6/7(x - (-3) =
y + 1 = 6/7(x + 3) <===
