Answer: SECON OPTION.

Step-by-step explanation:

The correct form to apply thee Distributive property is the shown below:

$\frac{(-3)(-8)}{8}+\frac{(-3)(-16d)}{8}+2d=24$

Keeping on mind that:

(-)(-)=+

You obtain:

$\frac{24}{8}+\frac{48}{8}d+2d=24$

Simpliying, the have:

$3+6d+2d=24$

Add the like terms and solve for d:

$8d=24-3\\8d=21\\d=\frac{21}{8}$

Therefore, you can conclude that Celia made the first error in STEP 1. She should have also distributed $-\frac{3}{8}$ over $-16d$ to get $3+6d+2d=24$ .

The cost of tuition at a 2 year school is $14,000 per academic year. Todd is eligible for $6,500 in financial aid to cover tuiti

emmainna [20.7K]

Answer:

$625

Step-by-step explanation:

If Todd has to pay $14,000 in tuition for his school each year and uses $6,500 in financial aid each year all for 2 years, the money he needs to save can be modeled by:

2(-$14000 + $6500) + 2(12x) = 0.

x is the minimum amount of money he needs to save in order to cover this expense without debt.

Thus 2(-$14000 + $6500) + 2(12x) = 0 →

2(-$7500) + 24x = 0 → -$15000 + 24x = 0 →

24x = $15000 → x = $625

Factor the expression completely. 625x4 - 256y4

scoundrel [369]

Answer:

(625 • (x4)) - 28y4

54x4 - 28y4 3.1 Factoring: 625x4-256y4

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 625 is the square of 25

Check : 256 is the square of 16

Check : x4 is the square of x2

Check : y4 is the square of y2

Factorization is : (25x2 + 16y2) • (25x2 - 16y2) 3.2 Factoring: 25x2 - 16y2

Check : 25 is the square of 5

Check : 16 is the square of 4

Check : x2 is the square of x1

Check : y2 is the square of y1

Factorization is : (5x + 4y) • (5x - 4y)this is the answer: (25x2 + 16y2) •(5x + 4y) • (5x - 4y)

Please help me ASAP!

Vsevolod [243]

Answer:

1. A=300miles B=300

2.A=50mph B=40mph

3.A=300miles B=200miles

Step-by-step explanation:

1.

Simply just read the graph

2.

do not let line B fool you, car b may look like it was faster, but unlike car a it started at 100 miles rather than 0 miles

3.

Just like 2, do not be fooled, you have to subtract to find b but a is easily found

I hope this helps u pls give a brainliest and a thx ;)

Answer:

Step-by-step explanation:

Angle E is congruent to angle C, so is the value required to make the sum of angles in triangle ABC be 180°.

∠E = 180° -118° -30° = 32°

The value of x is 32.
