Answer:
Question 1: RS=47
Question 2: x=6
Step-by-step explanation:
Question 1:
Step 1: 3x+5=2x+15+6x-37
Step 2: 3x+5=8x-22/2
Step 3: 3x+5=4x-11
Step 4: x=16
Step 5: 2(16)+15=32+15=47
<u>RS= 47</u>
<u />
Question 2:
Step 1: 7x+2+25x-14=180
Step 2: 32x-12=180
Step 3: 32x=192 (divide 32 from each side)
<u>x=6</u>

Answer:
what are the drop down words.
Im going to assume you know the formula.
sooo.
x= -11 +- √ (11)² -4 (1) (-15)
---------------------------------
2(1)
= -11 +- √121- (-60)
-------------------------
2
= -11 +- √181
-----------------
2
= -11 +- 13.45
-----------------
2
Either: Or:
X = -11 - 13.45
x = -11 + 13.45 ---------------
2
----- ----------
2
x = 1.23 x= -12.23
