your answer is 30

1^2 (raised to the power of 2) +2 is 3

5^2 +2 is 27

5^2=25

1^2=1

add 27+3=30

2w + 7 = 2(w + 5) - 8

BARSIC [14]

Answer:

no solution

Step-by-step explanation:

2w + 7 = 2(w + 5) - 8

Distribute

2w+7 = 2w+10-8

Combine like terms

2w+7 = 2w+2

Subtract 2w from each side

7 = 2

This is never true so there is no solution

Which equation is equivalent to<br><br> f(x) = 16x4 – 81 = 0?

Vesna [10]

Answer:

The equivalent expression is:

$16x^4-81=(4x^2-9)(4x^2+9)$

Step-by-step explanation:

We have been given the equation:

$f(x)=16x^4-81=0$

Equivalent expression can be computed by solving the expression ai its maximum.

We can factorize the given equation:

By using $a^2-b^2=(a+b)(a-b)$

Here, $a=4x^2,b=9$

Hence, we get the equation below:

$16x^4-81=(4x^2-9)(4x^2+9)$

Therefore, the equivalent expression is:

$16x^4-81=(4x^2-9)(4x^2+9)$

Someone help please!!!!

MAXImum [283]

Answer:

60cm²

Step-by-step explanation:

as the green and blue box are squares they will have the same sides, length.

so all the sides in the green and blue squares are 3

the pink and orange rectangles : the longer is 7 the shorter one is 3

for the top length of the whole shape is = 7 +3 = 10

side length of the shape is 3 + 3= 6

so then you do 6 x 10 = 60

60 cm² is the answer :)

Four times a number added to 3 times a larger number is 31. Seven subtracted from the larger number is equal to twice the smalle

Rus_ich [418]

Answer:

y = negative four-thirds x + StartFraction 31 Over 3 EndFraction

y = 2 x + 7

Step-by-step explanation:

Let x represent the smaller number and y represent the larger number.

Four times a number added to 3 times a larger number is 31.

<u>It is translated as:</u>

4x + 3y = 31

<u>Then, solving for y:</u>

4x + 3y=31 ⇒ 3y= -4x+31 ⇒ y= (-4x+31)/3 = - 4/3x + 31/3

⇒ y= - 4/3x + 31/3

<u>Correct answer choice for this equation:</u>

y = negative four-thirds x + StartFraction 31 Over 3 EndFraction

Seven subtracted from the larger number is equal to twice the smaller number.

<u>It is translated as:</u>

y-7= 2x

<u>Then, solving for y:</u>

y-7= 2x ⇒ y= 2x+ 7

<u>Correct answer choice for this equation:</u>

y = 2 x + 7
