STEP - BY - STEP EXPLANATION
Given:

Step 1
Suppose x= -3, then
x+ 3
Step 2
Divide the polynomial by (x+ 3)
Step 3
Determine the remainder and quotient from the above.
Quotient = x²+ x - 3
Remainder = 13
ANSWER
Quotient = x²+ x - 3
Remainder = 13
Answer:
98
Step-by-step explanation:
2(7*7)= 2*49=98
199.53 is correct. Brainliest?
-5 would be the y coordinate
<span>So, x+15 + 2x = 90 </span><span>
<span>Therefore 3x = 90 - 15 = 75 </span>
<span>and so x=25. </span>
<span>So the smaller angles are x+15 = 40 degrees and
2x=50 degrees. </span>
<span>So the larger one is 50 degrees.</span></span>
