Write an algebraic expression to represent the verbal statement: The product of the difference of m and 7 and 6.

photoshop1234 [79]

Answer:

(m-7) * 6

Step-by-step explanation:

you follow the statement from left to right. You see that there's a product so you write a product sign

then you know its the difference of m-7 on one side and 6 on the other getting

(m-7) * 6

Nico, Aditi, Erick, Raj, and Sandra are solving the equation.

Alex777 [14]

Answer:

Nico, Raj and Sandra are correct

Step-by-step explanation:

we have

$\frac{2}{5}(5+x)=8$

Method 1

Solve for x

That means ----> isolate the variable x

we have

$\frac{2}{5}(5+x)=8$

Multiply by 5/2 both sides

$(\frac{5}{2})\frac{2}{5}(5+x)=(\frac{5}{2})8$

$5+x=20$

subtract 6 both sides

$5+x-5=20-5$

$x=15$

Method 2

Solve for x

That means ----> isolate the variable x

we have

$\frac{2}{5}(5+x)=8$

Multiply by 1/2 both sides

$(\frac{1}{2})\frac{2}{5}(5+x)=(\frac{1}{2})8$

$\frac{1}{5}(5+x)=4$

Multiply by 5 both sides

$(5)\frac{1}{5}(5+x)=(5)4$

$5+x=20$

subtract 6 both sides

$5+x-5=20-5$

$x=15$

Method 3

Solve for x

That means ----> isolate the variable x

we have

$\frac{2}{5}(5+x)=8$

Apply distributive property left side

$\frac{2}{5}(5)+\frac{2}{5}(x)=8$

$2+\frac{2}{5}(x)=8$

subtract 2 both sides

$2+\frac{2}{5}(x)-2=8-2$

$\frac{2}{5}(x)=6$

Multiply by 5/2 both sides

$(\frac{5}{2})\frac{2}{5}(x)=(\frac{5}{2})6$

$x=15$

therefore

Nico, Raj and Sandra are correct

Simplify and write the answer in exponential form 3x^4 × y^4 x^4

RideAnS [48]

Answer:

The simplified expression in the exponential form will be: $3x^8y^4$

Step-by-step explanation:

Given the expression

$3x^4\times \:y^4x^4$

simplifying the expression and writing the answer in exponential form

$\mathrm{Apply\:exponent\:rule}:\quad \:a^b\times \:a^c=a^{b+c}$

$x^4x^4=x^{4+4}$

so the expression becomes

$3x^4\times \:y^4x^4=3x^{4+4}y^4$

$=3x^8y^4$ ∵ $\mathrm{Add\:the\:numbers:}\:4+4=8$

Therefore, the simplified expression in the exponential form will be: $3x^8y^4$

Please help me to solve this

zzz [600]

Answer:

Below in bold.

Step-by-step explanation:

First find the height by use Pythagoras theorem on the right triangle:

h = sqrt (5^2 - 4^2)

= sqrt 9

= 3.

Volume of the prism = area of the triangle * length

= 1/2 * 3 * 4 * 10

= 1/2 * 12 * 10

= 60 cm^3.

Total area = area of 2 triangles + area 0f 3 rectangles

= 2 * 1/2 * 3 * 4 + 3 * 10 + 4 * 10 + 5 * 10

= 12 + 30 + 40 + 50

= 132 cm^2.
