What is the answer to -7=-12 (-2)+B please help!

insens350 [35]

I would solve it for B, but that's just what I think. So you would do -12 time -2 which is 24, then subtract 24 from both sides so that you would get B=-31

(-4)(-4) use an exponent to rewrite the expression

DiKsa [7]

For this case we have the following expression:
 $(-4)(-4) 
$
By properties of exponents we have:
Same basis, the exponents are added.
We have then:
$(-4)^{1+1}$
Then, rewriting the exponent we have:
$(-4)^{2}$
Therefore, an exponent to rewrite the expression is:
2
Answer:
$(-4)^{2}$
an exponent to rewrite the expression is 2.

A cylinder holds 27.72 litres of water,when full.Find the hieght of the cylinder if the diameter is 42cm

krek1111 [17]

Answer:

27.72litres=27.72×1000 cm^3

(¡)Height of cylinder=27720×7/(22×21^2)=20cm

Step-by-step explanation:

(¡)First convert litres in to cm^3 take it as the volume of the cylindrical container

(¡¡)Then use V=22/7×r^2×h equation and substitute the values to V and r. Then find the value of h

#V=27.72×1000 (V= volume)

# r = 42/2=21 (r = radius)

Solve - 2x - 7 > X+ 8. O A. x<-3 O B. x<-5 O C. x>-5 O D. x>-3

Rzqust [24]

Answer:

x < -5

Step-by-step explanation:

- 2x - 7 > x+ 8

Add 2x to each side

- 2x+2x - 7 > x+2x+ 8

-7 > 3x+8

Subtract 8 from each side

-7-8 > 3x+8-8

-15 > 3x

Divide by 3

-15/3 > 3x/3

-5 >x

x < -5
