Step-by-step explanation:
total surface area of a cube = side × 6
25=side since all the sides of a cube are equal
25×6=
150cm
Answer:
Substitute point (4, 8)
y = y1 + m(x - x1)
y = 8 + m(x - 4)
y = 8 + mx - 4m
let m = 3 (It can be anything) Substitute m into equation:
y = 8 + (3)x - 4(3)
y = 2x - 4
Answer:
-2a +11b
Step-by-step explanation:
3(a+2b) - 5(a-b)
we apply distributive property:
3*a + 3*2b - 5*a + 5*b
3a+ 6b -5a +5b
-2a +11b
I’m pretty sure it’s y=-4x-16
Because the standard slope equation is y=mx+b and in perpendicular lines the slope is opposite of the slope on a parallel line. 0.25 is equal to 1/4 and the opposite of 1/4 is 4/1 but you also make it negative so it’s -4. So we have y=-4x+b and you plug in the coordinates and solve [8=-4(-6)+b and -4*-6=24 so you rewrite it as 8=24+b and 8-24=-16 and -16=b] so you plug in b and the equation is y=-4x-16
Hope this helped
