−8x2(2y − 3x) multiply

1 answer:

6 0

Distributive property
a(b+c)=ab+ac
also
$(x^m)(x^n)=x^{m+n}$
so

$-8x^2(2y-3x)=-8x^2(2y)-8x^2(-3x)$ =
$(-8)(x^2)(2)(y)+(-8)(x^2)(-3)(x^1)=-16x^2y+24x^3$

three consecutive integers can be represented by n, n+1 and n+2. if the sum of three consecutive integers is 57 what are the int

Paul [167]

18,19 and 20 are the integers.

Step-by-step explanation:

Given three integers are;

n, n+1, n+2

According to given statement;

n+(n+1)+(n+2)=57

$n+n+1+n+2=57\\3n+3=57\\3n=57-3\\3n=54\\Dividing\ both\ sides\ by\ 3\\\frac{3n}{3}=\frac{54}{3}\\n=18$

n=18

n+1 = 18+1 = 19

n+2 = 18+2 = 20

18,19 and 20 are the integers.

A triangle has an angle that measures 115°. The other two angles are in a ratio of 6:7. What are the measures of those two angle

ikadub [295]

Answer:

30° ; 35°

Step-by-step explanation:

Recall:

Sum of angles in a triangle = 180°

One of the 3 angles = 115

The sum of the other 2 Angles will be :

(180 - 115) = 65°

The other two angles are in the ratio 6:7

Hence,

Each of the two angles can be calculated thus :

Angle 2 :

Sum of ratio = 6 + 7 = 13

(6 / 13) * 65 = 30°

Second angle :

(7 / 13) * 65 = 35°
