85. i provided a picture just incase you needed your work shown.
<span>Volume of a square = (s)(s)(s) and s=5a+4b
Therefore: (5a+4b)(5a+4b)(5a+4b)=
(25a^2+40ab+16b^2)(5a+4b)=
(125a^3+200a^2b+80ab^2+100a^2b+160ab^2+64b^3)= (125a^3+300a^2b+240ab^2+64b^3)
You just multiple the first time the second and then do so again with the combination of the first two times the second. A little cleaning up and you are left with an equation in terms of a and b.</span>
Answer:
x=7
Step-by-step explanation:
We have been given all exterior angles of a quadrilateral which is a polynomial having 4 sides
We know that sum of all exterior angles of a regular polygon is always 360 degree.
So we can all given exterior angles and set it equal to 360
(12x+37)+(12x-2)+(46)+(20x-29)=360
12x+37+12x-2+46+20x-29=360
12x+12x+20x+37-2+46-29=360
44x+52=360
44x=360-52
44x=308
divide both sides by 44
x=7
<u>Hence final answer is x=7.</u>
Z= 138/625 or in decimal form it’s 0.2208
Answer:
Step-by-step explanation:
Multiplying Equation A by (1/3) and adding the result to Equation B will do the trick. Let's actually solve the problem!
Equation A: (5/3)x + 3y = 12
Equation B: 4x - 3y = 8
---------------------------
(5/3 + 12/3)x = 15 Note how this has eliminated the variable
(17/3)x = 15 y.
x = (3/17)(15)
