Select the pair of terms that are NOT like terms. a) 3x2 , 3x3 b) -7xy, -9yx c) 8b, -0.5b d) -p2q2 , (pq)2
Answers
Answer:
b), c), d)
Step-by-step explanation:
Like terms are terms that have same variables with same powers.
a)
[tex]3x^2,3x^3[/tex] have same variable [tex]x[/tex] with different powers.
So, [tex]3x^2,3x^3[/tex] are not like terms.
b) [tex]-7xy,-9yx[/tex]
Power of [tex]x[/tex] in each of the terms = 1
Power of [tex]y[/tex] in each of the terms = 1
[tex]-7xy,-9yx[/tex] are terms that have same variables [tex]\{x,y\}[/tex] with same powers.
So, [tex]-7xy,-9yx[/tex] are like terms.
c) [tex]8b,-0.5b[/tex]
Power of [tex]b[/tex] in each of the terms = 1
[tex]8b,-0.5b[/tex] are terms that have same variable [tex]b[/tex] with same power.
So, [tex]8b,-0.5b[/tex] are like terms.
d) [tex]-p^2q^2,(pq)^2=p^2q^2[/tex]
Power of [tex]p[/tex] in each of the terms = 1
Power of [tex]q[/tex] in each of the terms = 1
[tex]-p^2q^2,(pq)^2[/tex] are terms that have same variables [tex]\{p,q\}[/tex]with same powers.
So, [tex]-p^2q^2,(pq)^2[/tex] are like terms
If $18\sqrt 8-8\sqrt{18}=\sqrt n, what is n?
Answers
Answer:
288 trust me it is 100% right I tried it as an answer an got it right.
Step-by-step explanation:
Answer:
288
Step-by-step explanation:
From the first two parts of the problem, we have
18√8 - 8√18 = 36√2 - 24√2
= (36 - 24)√2
= 12√2.
Thus, we wish to solve for n in the equation 12√2 = √n. In other words, we want to know what number 12√2 is the square root of. Any nonnegative number is the square root of its own square, so
n = (12√2)²
= 12²(√2)²
= 144 ∙ 2
= 288.

Lisa had four candy bars . She ate 2 3/8 of the candy bars. How many candy bars does she have left.
Answers
Answer:
1 5/8
Step-by-step explanation:
You need to do the subtraction 4 - 2 3/8.
You can use mixed numerals, but you need to borrow and you need a common denominator.
4 - 2 3/8
Since 4 has no fraction part, we borrow 1 from 4 leaving 3. The 1 we borrow becomes a fraction written as 8/8, so we have the same denominator as the fraction 3/8.
Now we have
4 - 2 3/8 =
= 3 8/8 - 2 3/8
Subtract 2 from 3 to get 1.
Subtract 3/8 from 8/8 to get 5/8.
= 1 5/8
You can also set it up vertically as shown below and then subtract the whole numbers and subtract the fractions.

Which piece of information below will not help you prove that triangles ABC and DEF are congruent using ASA?
Answers
Answer:
A) [tex]AC=DF[/tex]
Step-by-step explanation:
Given
See attachment for triangles ABC and DEF
Options
A) [tex]AC=DF[/tex]
B) [tex]AB=DE[/tex]
C) [tex]\angle B=\angle E[/tex]
D) [tex]\angle A=\angle D[/tex]
Required
Which does not prove the congruence of ABC and DEF using ASA?
From the attachment, we have the following:
[tex]\angle A = \angle D[/tex] --- Angle
[tex]AB = DE[/tex] --- Side
[tex]\angle B = \angle E[/tex] ---- Angle
The ASA theorem means that 1 side of both triangles are equal.
By comparing the listed parameter to the options, we can see that options B, C and D prove that both triangles are congruent by ASA.
However, option A [tex]AC=DF[/tex] cannot be used because that will mean that two sides of both triangles are equal. This does not support the ASA theorem

possible number of learners in the
in a village, the bell rings every 30 minutes at the Junior School and every 40
minutes at the High School Both schools start lessons at 8:00 am
At what times between 8.00 am and 2.30p.m do the bells both rring
Answers
Find multiples of 30 and 40:
30: 30, 60, 90, 120, 150
40: 40, 80, 120, 160
The least common multiple is 120, so every 120 minutes they willl both ring.
1 hour = 60 minutes:
120/60 = 2 hours.
The bells ring together every 2 hours.
8 + 2 = 10 am
10 + = 12pm
12 + 2 = 2 pm
The bells will ring together at am, 12 pm and 2 pm.
Answer:
Solution :-At first common multiple of 30 an 40
[tex] \sf \to \: 30 = 30,60,90,120[/tex]
[tex] \sf \to \: 40 = 40,80,120[/tex]
Common Multiple = 120
Time taken = 120/60 = 2 hrs
Now,
8.00 + 2 = 10.00 am
10.00 + 2 = 12.00 noon
12.00 + 2 = 2.00 pm

2x > 3+5
2x>8
x>8/2

Answer:
x=17 and y=23 DONT SUE ME IF I GET THIS WRONG PLZZ ;-;
Step-by-step explanation:
Answer:
(1, - 1 )
Step-by-step explanation:
Given the 2 equations
3x - 2y = 5 → (1)
4x + 3y = 1 → (2)
Multiplying (1) by 3 and (2) by 2 and adding the result will eliminate y- term
9x - 6y = 15 → (3)
8x + 6y = 2 → (4)
Add (3) and (4) term by term to eliminate y
17x + 0 = 17
17x = 17 ( divide both sides by 17 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for y
Substituting into (2)
4(1) + 3y = 1
4 + 3y = 1 ( subtract 4 from both sides )
3y = - 3 ( divide both sides by 3 )
y = - 1
solution is (1, - 1 )

A water rocket is launched froni a platform. The height,
h in metres, of the water rocket at time & seconds after
it is launched is h= -212 + 74 + 4. When does the water
rocket hit the ground?
Answers
Answer:
4.41seconds later
Step-by-step explanation:
Let the equation of the height reached by the water front be h = -2t^2+7t+4
The water hits the ground at h =0
Substitute
0 = -2t^2+7t+4
-2t^2+7t+4 = 0
2t^2 - 7t - 8 = 0
t = 7±√(-7)²-4(2)(-8)/2(2)
t = 7±√49+64/4
t = 7±√113/4
t = 7±10.63/4
t = 7+10.63/4
t = 17.3/4
t = 4.41s
Hence the water hit the ground 4.41seconda later
