Answer:

The answer is A.

Step-by-step explanation:

You have to add up both polynomials together :

A = 7x² + 3xy

B = -3xy

A + B = 7x² + 3xy + (-3xy)

= 7x² + 3xy - 3xy

= 7x²

Chords and intersect in circle O as shown in the diagram. Two of the angle measurements are marked. What is mCED?

jenyasd209 [6]

we know that

The measure of the interior angle is the half sum of the arcs comprising it and its opposite

m∠CED= $\frac{1}{2} *(arc\ AB+arc\ CD)$

see the attached figure with letters to better understand the problem

$arc\ AB=82$ ° ------> by central angle

$arc\ CD=48$ ° ------> by central angle

Substitute the values in the formula above

m∠CED= $\frac{1}{2} *(82+48)$

m∠CED= $\frac{1}{2} *130$

m∠CED= $65$ °

therefore

<u>the answer is</u>

m∠CED= $65$ °

Solve the simultaneous equation: x-y=2

kakasveta [241]

Answer:

Y= –7.08, 5.08

Step-by-step explanation:

hope ya ready bro.

X=36/Y

replace 36/y instead of X

36/Y–Y=2===> 36–Y²=2Y===> Y²+2Y–36=0

Y1= –1+√37≈ –7.08

Y2= –1–√37≈ 5.08
