**Answer:remember that perpendicular lines have slopes that multiply to -1**

**y-y_1=m(x-x_1) is point-slope form**

**in point-slope form, it passes through the point (x_1,y_1) and has a slope of m**

**we want to find the equaiton of the line that is perpendicular to y-3=-4(x+2) and passes through (-5,7)**

**we need the slope**

**y-3=-4(x+2)**

**the slope is -4, but we want perpendicular so**

**-4 times what=-1?**

**divide both sides by -4**

**what=1/4**

**so the slope of our mystery line is 1/4 and it passe through (-5,7)**

**so we can write in point slope form as y-7=\frac{1}{4}(x-(-5)) or y-7=\frac{1}{4}(x+5)**

**the equation is y-7=\frac{1}{4}(x+5)**

**Step-by-step explanation:**

act like it's a fraction you multiply the top number by the bottom number (numerator and the denominator)and then the other but it is keep change flip the same way with the first numbers

The volume formula is area of base×height. In this case, we are working with rectangles, so the formula is l×w×h. We have to find the volume of each block and add them together. Top rectangle: 12×30×4=1440. Middle rectangle: 30×36×4=4320. Bottom rectangle: 30×60×4=7200. 7200+4320+1440=12960 inches squared.
