How subtracting polynomials differs from adding polynomials and examples?

1 answer:

Llana [10]3 years ago

All you need to do is distribute the subtraction sign to all of the numbers in the polynomial being subtracted. Ex: (6x^4+8x^3-3)-(2x^2-9x+9) you distribute the subtraction sign in the (2x^2-9x+9) and get -2x^2+9x-9. Next, all you have to do is combine like terms. 6x^4+8x^3-3-2x^2+9x-9 Turns into 6x^4+8x^3-2x^2+9x-12

What is the measure of X PLZ HELP - thank you and much love ;)

never [62]

Answer:

x = 17

Step-by-step explanation:

∠6 and ∠7 are vertically opposite angles and thus are congruent, hence

4x = 2x + 34 ( subtract 2x from both sides )

2x = 34 ( divide both sides by 2 )

x = 17

Consider the function f(x) =2x-6 find f(2)

tester [92]

Step-by-step explanation:

✧ $\underline{ \underline{ \large{ \tt{G \: I \: V \: E\: N}}} } :$

f ( x ) = 2x - 6

✧ $\underline{ \underline{ \large{ \tt{T\: O \: \: F\: I\: N\: D}}}}:$

value of f ( 2 )

✧ $\underline{ \underline{ \large{ \tt{S \:O \: L \: U \: T \: I \: O \: N}}}} :$

❀ $\large{ \text{When \: x = 2 ,\: f}(2) = 2 \tt{ \times 2 - 6}}$

⟼ $\large{ \text{f(2) = 4 - 6 = \boxed{ \large{ \text{ - 2}}}}}$

♨ $\boxed{ \boxed{ \large{ \text{OUR\: FINAL \: ANSWER : \boxed{ \underline{ \bold{ \text{ - 2}}}}}}}}$

NEED HELP ASAP PLEASE

Ilya [14]

Answer:

see explanation

Step-by-step explanation:

Given

A = $\frac{1}{2}$ bh

a. substitute b = 6 and h = 5 into the formula

A = $\frac{1}{2}$ × 6 × 5 = $\frac{1}{2}$ × 30 = 15 units²

b.

Multiply both sides of the formula by 2

2A = bh, that is

bh = 2A ← divide both sides by b

h = $\frac{2A}{b}$ = $\frac{2(16)}{4}$ = $\frac{32}{4}$ = 8

c

Using

bh = 2A ← divide both sides by h

b = $\frac{2A}{h}$ = $\frac{2(12)}{4}$ = $\frac{24}{4}$ = 6

Answer:

x≈231.123

Step-by-step explanation:

1) Make a ratio 314/2512= x/1584

2) Use the concept of cross multiplication and get 314*1584=2512x

3) Use Algebra:

314*1584=497,376

497,376/2152=2512x/2152

x≈231.123
