Answer:
A) 684 in^2
Step-by-step explanation:
Since it needs to be painted all around the box we have to find the surface area of the box
The surface area of cuboid is
=2lw+2lh+2hw (l: length, w: width, h: height)
=2×15×12+2×6×15+2×6×12
= 684 in^2
Answer:y=x-2
Step-by-step explanation:the reciprocal of -x is simply x therefore making y=x-2 perpendicular to y=x-2
Answer:
Hey, do you know how to screenshot images? There is also a website for Brainly if needed
Step-by-step explanation:
Verify each of the solutions by substituting them back into the original equation <span><span>log<span>(−2a+9)</span>=log<span>(7−4a)</span></span><span>log<span>(-2a+9)</span>=log<span>(7-4a)</span></span></span> and solving. In this case, all solutions were found to be valid.<span>a=−<span>1</span></span>
Slope m=(y2-y1)/(x2-x1)=(10-4)/(4-2)=6/2=3
y = mx+b
y=3x+b
Take point (2,4),
4=3*2+b
4=6+b
b=-2
y=3x-2
Answer is D. <span>y = 3x − 2</span>
