Answer: C. rationalizing the denominator
Rationalizing the denominator is a useful step to simplify expressions where there are square roots in the denominator. It doesn't apply to actually solving a quadratic. On the other hand, the quadratic formula can solve quadratics. The same applies for choices B and D as well.
we're doing literal equations in math and i dont understand how i would solve this question, please help!
Answer:
x = -4u/3
Step-by-step explanation:
The first step is to create a fraction on both sides in order to prepare for cross-multiplication.
Cross-multiplication is a shortcut for the following technique, shown by this example.
a/b=c/d
Multiplying both sides of the equation by bd using the multiplication property of equality will then grant the equation ad = bc, and then a single component can be isolated by creating the equation a = bc/d for example using the division property of equality.
Back to cross-multiplication, however, creating a fraction of both sides can be achieved by creating the equation u/1 = -3x/4, since any number divided by 1 is equal to itself.
Then, by cross-multiplying u and 4 and 1 and -3x, you get the equation 4u = -3x.
Dividing both sides by -3 will then grant the final answer of x = -4u/3.

you show what operation you perform to both sides of the equation for every step.
Answer:
6
Step-by-step explanation:
7x + 3(-x + 6) = 42
use distributive property
7x + -3x + 18 = 42
positive + negative = negative
7x - 3x + 18 = 42
combine like terms
4x + 18 = 42
subtract 18 from both sides
4x + 18 - 18 = 42 - 18
18 is canceled out on the left side
4x + 0 = 24
4x = 24
divide both sides by 4
4x ÷ 4 = 24 ÷ 4
1x = 6
x = 6

You want to purchase your first house. A conventional mortgage will require a credit score of approximately 630. Your credit score is 560. You need to increase it by 70 points to get to 630. If you increase your score by 12% per year, how many years will it take to lift your score to 630?
Answer:
a) 1.1 yrs
Step-by-step explanation:
THESE ARE OPTIONS FOR THE QUESTION BELOW;
a) 1.1 yrs
b) 2.3 yrs
c) 26 yrs.
d) 12 yrs.
✓At initial year (0 year) credit score =560 points
Then the score is increased by 12% per year, with this 12% increase we have 702.4 points in the 1st year
✓At the first year(1st year)
(12/100)× 560 points of the initial year.
= 627points
✓ At second year (2nd year), the 627points
increases by 12% again.
(12/100)× 627.2 points of the initial year.
= 702.4points
There was 75.2 increase between istyear and second year(702.4points - 627points)
Since, We have 12 month in a year, that means there is 6.2 points per month (75.2/12) for the year .
After second year we had 627points, with increase of 6.2point, Then at 1.1 year we would have score of 630 points

what is the value of x?
Answer:
The value of x is 8 cm
Step-by-step explanation:
we can see that there are two triangles
smaller triangle and larger triangle
and both triangles are similar
so, the ratio of their sides must be equal
we get
now, we can solve for x
we can cross multiply
Divide both sides by 5
Subtract both sides by 13
divide both sides by 2

Step-by-step explanation:
TV−→− bisects ∠STU, m∠STV=(14x+8)∘, and m∠UTV=(x+2)∘. Find m∠STU
Answer:
Since TV bisects STU, m∠STV and m∠UTV are equal
14x+8 = x+2
13x+8 = 2
13x = -6
x = -6/13 or -0.46
The measure of m∠STU is 40/13 degrees
A point that bisects a line divides the line into two equal parts
If TV bisects ∠STU and ∠UTV, then;
∠STU = ∠STV+ ∠UTV ∠STV= ∠UTVGiven the following
m∠STV=(14x+8)∘
m∠UTV=(x+2)∘
Substitute the given values into the formula and calculate m∠STU
14x + 8 = x+ 2
14x - x = 2 - 8
13x = -6
x = -6/13
Get m∠STV
m∠STU = 14x+8 + x + 2
m∠STU = 15x + 10
m∠STU = 15(-6/13) + 10
m∠STU = -90/13 + 10
m∠STU = 40/13
Hence the measure of m∠STU is 40/13 degrees
