What’s the answer to this question ?

Dmitry [639]

Answer = 121°

Parallelograms’ angles are all equal. So the two given are equal.

6x + 13 = 7x - 5
x = 18

Plug x back into one of the original angles

6(18) + 13 = 121

Now we know all the angles are 121°, so that’s the answer

−3 2/7−(−5/7) plz help me

balu736 [363]

Answer:

-2 or -14/7 (they're the same)

Step-by-step explanation:

Write it out: $-3\frac{2}{7} - (-\frac{5}{7})$
Simplify. It should now look like this: $-3\frac{2}{7} + \frac{5}{7}$
Turn -3 2/7 into an improper fraction. It should now look like this: -19/7
Add: $-\frac{19}{7} + \frac{5}{7} = -\frac{14}{7} = -2$

I hope this helps!

(ab^2 x -b^4a^3)^2<br><br> What is the answers

Umnica [9.8K]

Answer:

$\left(ab^2x-b^4a^3\right)^2:\quad a^2b^4x^2-2a^4b^6x+a^6b^8$

Step-by-step explanation:

Given the expression

$\left(ab^2\:x\:-b^4a^3\right)^2$

solving the expression

$\left(ab^2\:x\:-b^4a^3\right)^2$

$\mathrm{Apply\:Perfect\:Square\:Formula}:\quad \left(a-b\right)^2=a^2-2ab+b^2$

$a=ab^2x,\:\:b=b^4a^3$

so the expression becomes

$=\left(ab^2x\right)^2-2ab^2xb^4a^3+\left(b^4a^3\right)^2$

$=a^2b^4x^2-2a^4b^6x+a^6b^8$

Thus,

$\left(ab^2x-b^4a^3\right)^2:\quad a^2b^4x^2-2a^4b^6x+a^6b^8$
