Answer:

$15d^1^3$

Step-by-step explanation:

$(5d^6)(3d^7)\\\\= 5*3*d^6*d^7\\\\= 15*d^6^+^7\\\\= 15d^1^3$

Important things to note:

- The 5 and 3 are multiplied together because they are both regular numbers

- The $d^6$ and $d^7$ are multiplied together because they are they same variable

- When multiplying values with exponents, the exponents are added together

The perimeters of the square and the triangle shown below are equal. What is the value of x?

Rudiy27

Perimeter is the sum of all the sides. So we can set up an equation:

$\sf 3x+1+3x+1+3x+1+3x+1=2x+8+x+8+4x+2$

Now solve for 'x', combine like terms:

When it comes to terms with variables it's just like normal addition but we keep the variable:

$\sf 3x+3x+3x+3x=12x$
$\sf 2x+x+4x=7x$

So we have:

$\sf 12x+1+1+1+1=7x+8+8+2$

Add:

$\sf 12x+4=7x+18$

Subtract 7x to both sides:

$\sf 5x+4=18$

Subtract 4 to both sides:

$\sf 5x=14$

Divide 5 to both sides:

$\boxed{\sf x=2.8}$

Find the measure of angle XAZ in the figure below.

Bess [88]

Answer:

m∠XAZ = 40°

Step-by-step explanation:

Since ∠YAU, ∠YAZ and ∠XAZ are the angles based at a point on a straight line, and the sum of the all angles on a line is 180°.

Therefore, m∠YAU + m∠YAZ + m∠XAZ = 180°

50° + 90° + m∠XAZ = 180°

m∠XAZ = 180° - 140°

= 40°

Therefore, measure of angle XAZ is 40°.

What is the coefficient of y in the expression 2 ⋅ 4 + 3y?

svet-max [94.6K]

A coefficient is the number that is multiplied by the variable (the letter).
so the coefficient in ur expression is 3.

the 2 and the 4 are constants...because they are numbers with no variables
