Answer:
D
Step-by-step explanation:
Let's solve your equation step-by-step.
x2+4=3x+8
Step 1: Subtract 3x+8 from both sides.
x2+4−(3x+8)=3x+8−(3x+8)
x2−3x−4=0
Step 2: Factor left side of equation.
(x+1)(x−4)=0
Step 3: Set factors equal to 0.
x+1=0 or x−4=0
x=−1 or x=4
Answer:
x=−1 or x=4
Answer:
$10.06
Step-by-step explanation:
Tax rate = 6% , convert into 0.06

Answer:
37.5 square units
Step-by-step explanation:
Given:
A(-6,-4), B(6,5), C(-1,6), and D(2, 2), where CD is the altitude if ∆ABC
Required:
Area of ∆ABC
SOLUTION:
Area of a ∆ABC =½*AB*CD
✍️



✍️



✍️Area of a ∆ABC =½*AB*CD
= ½*15*5
✅ Area = 37.5 square units
SS tax is 6.2% of 1,047.30
In math "of" means times, so
.062 x 1047.30 = 64.9326
Rounded to the nearest cent $64.93
The Priority is always to parenthesis. It means that in both equations, begin by operating what's inside the parenthesis. Then Subtract what's left.
For the first one you get:



For the second one you get:



Which mean that The 2 equations are not equal, because

Hope this Helps! :D
