Answer:
29 + 8x
Step-by-step explanation:
5 + 8(3 + x) by PEDMAS parentheses first
= 5 + 3(8) + x(8)
= 5 + 24 + 8x
= 29 + 8x
Answer: x-intercept is -9
Step-by-step explanation: To find the x intercept y is 0 and to find the y intercept x is 0. 18 divided by -2 is -9, which is the answer
Answer:
<h2>12 + 20 = 4 × (3 + 5)</h2>
Step-by-step explanation:
12 = 4 × 3
20 = 4 × 5
12 + 20 = 4 × 3 + 4 × 5 = 4 × (3 + 5)
Answer:
1. Yes
2. No
2. Yes
4. Yes
5. Yes
Step-by-step explanation:
The angles in the first pair are congruent and 40° each (XYZ and XYW are complementary)
Segment FG is 4 cm while segment DE is 6 cm so they are not congruent
As shown on the figure both segment OR and segment OS is 2 in. long
Angle 2 and angle 4 are congruent
Angle ROQ and angle ROP are congruent because all angles shown on the figure has a measure of 90°

Answer:
a[n] = n^2 -3n -6
Step-by-step explanation:
First differences are ...
-8 -(-8) = 0
-6 -(-8) = 2
-2 -(-6) = 4
Second differences are ...
2 -0 = 2
4 -2 = 2
Constant second differences indicate a degree 2 (quadratic) sequence.
The general formulation can be written as ...
an = a1 +(n -1)(d1 +(n -2)/2(d2)) . . . . where a1 is the first term; d1 is the first first difference; d2 is the second difference
= -8 +(n -1)(0 +(n -2)/2(2)) = -8 +(n -1)(n -2)
an = n^2 -3n -6 . . . . . formula for the n-th term
