3 more means adding 3
The product of 5 and a number is 5n because you're multiplying a number and 5.

Angle W is 125 degrees since the two have to add up to 360, since they form a whole, round angle.
Angle Y is 138 degrees, since the two angles there form a straight line, making a total of 180, then subtracting 42 to find y.
Angle X is 50 degrees, since in the diagram, it shows that the two angles form a right angle, giving it a total of 90 degrees. Then all you have to do is subtract 40.
Now, for Angle Z, you have to add up all the angles you know in shape B, which is 125+138+40=303. Now, since all quadrilaterals interior angles add up to 360 degrees, you do 360-303=57. So, Angle Z =57

What is the following is the solution to the equation 25^(z+2) = 125

maksim [4K]

First, rewrite the equation $25^{z+2} = 125$ with the base equal to 5. Note that:

$25=5^2;$
$125=5^3;$
$25^{z+2}=(5^2)^{z+2}=5^{2\cdot (z+2)}.$

Then

$5^{2\cdot (z+2)}=5^3.$

Since the bases are equal, you have that powers are equal too:

$2\cdot (z+2)=3,\\ \\2z+4=3,\\ \\2z=3-4,\\ \\2z=-1,\\ \\z=-\dfrac{1}{2}.$

Answer: $z=-\dfrac{1}{2}.$

Students were asked to write 6x5 + 8x - 3x3 + 7x7 in standard form.

dimulka [17.4K]

Answer:

$7x^{7} + 6x^{5} - 3x^{3} + 8x$

Step-by-step explanation:

Students are asked to write $6x^{5} + 8x - 3x^{3} + 7x^{7}$ in the standard form.

Now, in the standard form of a polynomial the highest power of the variable takes the leftmost position and the lowest power of the variable takes the rightmost position and the power of variable decreases from left to right.

Therefore, the standard form will be $7x^{7} + 6x^{5} - 3x^{3} + 8x$ . (Answer)
