Answer:
y= 28/17
x= 57/17
Step-by-step explanation:
5x + 2y = 22
-2x + 6y = 3
(2)(5x + 2y = 22)→ 10x + 4y = 44
(5)(-2x + 6y = 3)→ -10x +30y = 15
Add this last eq → 34y=56 → y= 28/17
Replace this in any equation
-2x + 6(28/17) = 3 → x= - (54/17-168/17)/2 = 57/17
angle A measure 50 defree and angle B measure 40 degrees
3 to 9
theres a few calculaters that can do that
Answer is x² + 2x + 5
<u>Step-by-step explanation:</u>
Step 1:
Add the two polynomials
⇒ (2x + 7) + (x² - 2) = 2x + 7 + x² - 2 = x² + 2x + 5
