Answer:
v = 60
Step-by-step explanation:
65 + 55 + v = 180
65 + 55 = 120
180 - 120 = 60
v = 60
Answer:
two quadratic functions combined by addition
a linear function and a quadratic function combined by addition
two linear functions combined by multiplication
Step-by-step explanation:
-3x² + 5
(-4x² + 4) + (x² + 1)
-3x² + 5
(-3x² - x) + (x + 5)
-3x² + 5
(sqrt(5) - sqrt(3)x)(sqrt(5) + sqrt(3)x)
Answer:If we got 560 pounds for 800 dollars and x pounds for 1 dollar, this means that x = 560*1/800 <=> x = 56/80. Performing the calulation we get that x = 0.7 . So the right answer is the final one.

Answer:
1. 31.25 square m, 2. S=478 square m, 3. 6.25 square m
Step-by-step explanation:
------------------- Surface Area of the Rectangular Prism(2ND ANSWER)
S=2(lw)+2(lh)+2(wh)
S=2(11*9)+2(7*11)+2(7*9)
S=2(99)+2(77)+2(63)
S=198+154+126
S=478 square m
--------------------- Surface area of Cube(1ST ANSWER)
S=6(lw) -2.5^2
S=6(6.25)-6.25(overlapping area A)
S=5(6.25)
S=31.25 square m
-------------------------------------------------- Overlapping area A(3RD ANSWER)
-> 6.25 square m
--------------------------------------------------- Surface area of composite figure(4th ANSWER)
=478+37.5-2(2.5)
