Answer: no
I would not flip the inequality symbol
Answer:
The answer to your question is: 83 + 6
Step-by-step explanation:
This is a square of a binomial.
(2
+ 3
1.- Square of the first term
( 2
= 4(5) = 20
2.- Twice the product of the two terms
(2)(2
(3
= 6
3.- Square of the second term
(3
= 9(7) = 63
4.- Write the solution
20 + 6
+ 63
83 + 6
(-35-42-63)/7= (-140)/7=-20
Roots of the equation 3x² -3x-6=0 are -1 and 2,
all choices are given wrong
3*2²-3*2-6=0
12-6-6=0
0=0, which is true , so root is 2
3*20²-3*20-6=0
600-60-6=0
534=0 which is wrong, so root is 2, but not 20
23) Store A: y=6.30÷2
y=3.15
Store B: y=3.2
Store C: y=3.25x
y=3.25 so Store A sells the cheapest so (A) is the answer
24) the area uses half of the diameter, not the whole diameter. so the answer is 5.5pi^2 (B)
25) 1/2 × 1/2 = 1/4 × 1/2 = 1/8 (D)
26) was done correctly and (D) is the correct answer
27) 2 (x-3) +1 =19
2 (x-3) = 19 - 1
(x-3) = 18 ÷ 2
x-3 = 9
x= 9+3
x=12 (D)
