X is the a multiply 1 5 time hope it hopefull
The answer to 1 is segment CB the answer to 2 is equal to 6 and I think the answer to 3 is 3
Answer:
Step-by-step explanation:
Set the two unknown numbers to X and Y.
X + Y = 22
2X = 10Y
Rewrite the second equation as: X = 5Y
Now use this in the first equation: 6Y=22
Y = 3.67 [3 2/3]
X = 18.33 [18 1/3]
---------------------------------------
3 2/3 + 18 1/3 = 22, and
2*(18 1/3) = 10*(3 2/3)
Answer:
Step-by-step explanation:
AR = QR = RS = (1/2) QS = 3
So ....by the Pythagorean Theorem, AS = AQ =
√ [3^2 + 3^2] = √[9 + 9 ] = √18
And the area of the two semi-circles= the area of a circle with a radius of AS/2 =
pi [AS/2]^2 =
pi [√18/2]^2 = 18pi/4 = (9/2)pi units^2
And the area of the rest of the figure is just that of a rhombus =
The product of the diagonals / 2 =
AB*QS/2 = 9 * 6 / 2 = 27 units^2
So....the total area =
[(9/2) pi + 27] units^2 = about = 41.1 units^2 [rounded]
(f+g)(x) is simply saying add these two problems together.
(2x+6) + (4x^2)
Parenthesis are now useless, as there is only addition.
2x + 6 + 4x^2
Reorder, cause it's pretty and familiar
4x^2 + 2x + 6
We could further simplify
2(2x^2 + x + 3)
