Answer:
21√(5(
Step-by-step explanation:
6√(9*5)
6*3√(5)
18√(5) + 3√(5) = 21√(5(
First, you substitute each x in the first equation- 2(2y+10)-3y=17
Next, simplify - 4y+20-3y=17
y+20=17
y=-3
Next, substitute the y in for the second equation, x=2y+10
x=2(-3)+10
x=-6+10
x=4
ANswer:
x=4
y=-3
Hope this helps!
L*w=6*20
6*15= 90m
20*15=300m
l*w= 90*300=27000m <-- area
We can usually get a couple of facts for these that let us rule out answers without working out all the details.
The green and red areas are below a CUP parabola, opening up. CUP stands for concave up positive, and tells us there's a positive coefficient on x². Unfortunately all the choices have a positive 1 coefficient, no help here.
Since the areas are below they're going to be y ≤ x² + other stuff. That rules out B and C.
The red and blue parts are below the line, and the line has a positive slope. So that's y ≤ mx + b where m>0 is the positive slope. That rules out D with the negative slope.
Answer: A
Answer:
the correct option is D (12 units, 14 units, 10 units)
Step-by-step explanation:
P= 36
2t + 2 + 2t + 4 +2t = 36
combine like terms
6t + 6 = 36
subtract 6 from both sides
6t = 30
30/6 = 5
T = 5 so plug the t in the other equations
2(5) + 2 = 10 + 2 = 12
2(5) + 4 = 10 + 4 = 14
2(5) = 10
To check combine all the numbers above and you would get 36
