So we can use the formula 2lw +2wh+ 2lh, which is the surface area formula and we can set that to equal 20. 2lw +2wh+ 2lh=20
lw+wh+lh= 10
Let’s isolate L
Lw+Lh=10-wh
Let’s distribute L
L(w+h)=10-wh
L=(10-wh)/(w+h)
You can use this formula to plug in values for w and h and it will work as long as their products are less than 10
Answer:
wheres the question. that's just a topic
Only the third model shows parallel lines cut by a transversal.
We can solve this problem by using some properties that parallel lines cut by a transversal have. First of all, corresponding angles are congruent, and since the angles in figure 1 are corresponding but not congruent, that means that figure one is out.
In addition, in figure two, alternate exterior and interior angles of parallel lines intersected by a transversal are congruent, so since they are not in the picture, that means that this figure is also out.
Figure three is correct because since those are same side interior angles, they need to be supplementary for those to be two parallel lines intersected by a transversal. Since they do, in fact, add up to 180°, that means that the answer is figure three.
Y = 5x + 3
when x = 4
y = 5(4) + 3 = 23
Answer (4,23)
Answer: Yes, it is 
Step-by-step explanation:
To simplify square roots, you can factor the number inside the square root into its lowest common denominators.
Any value that appears twice can be "taken out" of the square root and moved to the left of it:
,
What you are doing is essentially taking the square root of 4 and the square root of 3. Because the square root of 4 can be simplified, and the square root of 3 cannot, this is the most simplified version of the expression we can reach.
