Answer:

$\frac{x-2}{x+3}$

Step-by-step explanation:

given $\frac{(x-3)(x-2)}{(x+3)(x-3)}$

the factor (x - 3) can be cancelled from the numerator/ denominator leaving

$\frac{x-2}{x+3}$

Pyramid A and Pyramid B are similar. Pyramid A has a volume of 648 m and Pyramid B has a

ryzh [129]

Answer:

the ratio of the surface area of Pyramid A to Pyramid B is: $\frac{36}{49}$

Step-by-step explanation:

Given the information:

Pyramid A : 648 $m^{3}$
Pyramid B : 1,029 $m^{3}$
Pyramid A and Pyramid B are similar

As we know that:

If two solids are similar, then the ratio of their volumes is equal to the cube

of the ratio of their corresponding linear measures.

<=> $\frac{Volume of A }{Volume of B}$ = $(\frac{a}{b}) ^{3}$ = $\frac{684}{1029}$ = $\frac{216}{343}$

<=> $\frac{a}{b} =$ $\frac{6}{7}$

Howver, If two solids are similar, then the n ratio of their surface areas is equal to the square of the ratio of their corresponding linear measures

<=> $\frac{surface area of A}{surface area of B} =( \frac{a}{b}) ^{2}$

= $\frac{36}{49}$

So the ratio of the surface area of Pyramid A to Pyramid B is: $\frac{36}{49}$

Write an equation in slope-intercept form for the line that is parallel to the line y = -4x + 5 and that passes through the give

harkovskaia [24]

Since we know the slope intercept form is y=mx+b and that parallel lines have the same slope we know that the slope in our equation is going to be -4
we can plug in the point (-8,5) into y= -4x+b
in doing that we get 5= -4(-8)+b.
5=-4(-8)+b
5=32+b
subtract 32 from both sides to find b the (y-intercept)
5-32=-27
b=-27
bc the slope is -4 and the y-intercept is -27 the equation of the line that's parallel to y=-4x+5 and passes through the given point (-8,5) is y=-4x-27
