(y^2)^2 + 14y^2 +49

Rewrite 49 as 7^2

(y^2)^2 + 14y^2 +7^2

Factor using the perfect square rule.

Final answer: (y^2 + 7)^2

Are the ratios 2:3 and 12:18 equivalent?

lesya692 [45]

Answer: Yes

Step-by-step explanation:

Yes, they are, because if you multiply 2*6=12 and 3*6=18, so here we multiplied both 2 and 3 by the same number (6) and we got the same result 12:18. This method also works with fractions.

What is the sum of the finite arithmetic series (-5)+0+5+10+ ......+65

Alex17521 [72]

If you want to solve this problem using formulas, there are two important formulas:

t1 = first term = -5

tn = nth term = last term = -5

n = numbr of terms

Sn = sum of the n terms

tn = t1 + (n - 1)d ---> 65 = -5 + (n - 1)(5)

65 = -5 + 5n - 5

65 = -10 + 5n

75 = 5n

n = 15

Sn = n(t1 + tn)/2 ---> Sn = 15(-5 + 65)/2

Sn = 450

So ur answer rounds up to 450

For Spirit Day, each 8th-grade homeroom designs a unique twocolor T-shirt. They get to choose from the colors red (R), blue (B),

ratelena [41]

Answer:

P(B and V)=10%

Step-by-step explanation:To solve this poroblema we use the formula of combinations:

C(n,r)=(nr)=n!(r!(n−r)!)

Where n is the number of objects that can be chosen and you choose r from them.

There are 5 colors of shirts.

The number of shirts that can be made by combining 2 of the 5 possible colors is calculated as:

5C2= $\frac{5!}{2!(5-2)!}$

5C2=10

The number of shirts that can be made by combining 2 of the 2 possible colors (B) and (V) is calculated as:

2C2=1

Then the probability is:

P( B and V)= $\frac{1}{10}$

=0.1= 10%

$\frac{2C2}{5C2}$

Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points. What would be

sdas [7]

Answer:

Mia's test score is 44 if she got 3 questions wrong.

Mia's test score is (50-2x) if she got x questions wrong.

Step-by-step explanation:

It is given that, Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points.

If she got 3 questions wrong, then

Deducted marks $=2\times 3=6$

Marks obtained by Mia = Total marks - Deducted marks

$=50-6$

$=44$

So, Mia's test score is 44 if she got 3 questions wrong.

If she got x questions wrong, then

Deducted marks $=2\times x=2x$

Marks obtained by Mia = Total marks - Deducted marks

$=50-2x$

So, Mia's test score is (50-2x) if she got x questions wrong.
