Answer:

7x^2 + 7

Step-by-step explanation:

So you collect the "like-terms". 3x^2 is not the same as 7, however, 4x^2 has the same term as 3x^2, so you add those together and then join the 7 in the expression.

Hope that explanation makes sense

Answer:

$3x^{2} + 4 {x}^{2} + 7 = 7 {x}^{4} + 7$

Step-by-step explanation:

Because 3x² and 4x² are like terms, they can be added together:

3+4=7

²+²=⁴

Therefore, it will be 7x⁴.

But 7x⁴ and 7 are not like terms. So it is just 7x⁴+7

What is Q=R+Rst; solve for s

oksano4ka [1.4K]

Step-by-step explanation:

q=r+rst

Rewrite the equation as

r+rst=q

Subtract r from both sides of the equation.

r st=q−r

Divide each term by rt

(r st )/rt=(q/rt)−(r/rt)

Cancel the common factor.

(

s=(q/rt)−1/t

Can someone help me?

Rasek [7]

Step-by-step explanation:

$given \: - 5n = 4m$

making m the subject first by dividing through by 4

$\frac{ - 5}{n} = \frac{4m}{4}$

$m = \frac{ - 5n}{4}$

from the question, given n = -1 ,0 ,1

so when n= -1

$m = \frac{ - 5( - 1)}{4}$

$m = \frac{5}{4}$

when n=0

$m = \frac{ - 5(0)}{4}$

$m = \frac{0}{4}$

$m = 0$

when n=1

$m = \frac{ - 5(1)}{4}$

$m = \frac{ - 5}{4}$

Answer:

x = 27°

Step-by-step explanation:

m<D

m<CBE = 63° (Given)

m<CBE = m<ABD (vertical angles)

m<ABD = 63° (substitution)

x = 180 - (m<ABD + m<D) (Sum of triangle)

x = 180 - (90 + 63)

x = 27°
