8x−65−(−x2)=−x2−(−x2)

x2+8x−65=0

(x−5)(x+13)=0

x−5=0 or x+13=0

x=5 or x=−13

Find the volume length 10 2/5 cm, width 3 cm, height 8 1/3 cm

AURORKA [14]

Answer:

260 cm

Step-by-step explanation:

formula for finding volume:

l=length w=width h=height v=volume

$10\frac{2}{5}$ × 3 × $8\frac{1}{3}$

$10\frac{2}{5}$ = $\frac{52}{5}$

how did i do that?

cross multiply the whole number and the denominator together and add the product by the numerator.

$8\frac{1}{3}$ = $\frac{25}{3}$

so, $\frac{52}{5}$ × $\frac{25}{3}$ × $\frac{3}{1}$

cross simplify(dont have to do it just makes everything easier)

and you get:

$\frac{52}{1}$ × $\frac{5}{1}$ × $\frac{1}{1}$

and you get $\frac{260}{1}$

$\frac{260}{1}$ = 260 cm

What would be the equation for this line?

Nata [24]

Answer:

y = -x -2

Step-by-step explanation:

The line goes down 1 grid square for each grid square to the right. Hence its slope is -1. The graph shows the y-intercept to be -2, so the slope-intercept equation with m = -1 and b = -2 is ...

y = mx + b

y = -x -2
