Simplify the expression.
5(z+4)+5(2-z)
Answer:30
Step-by-step explanation:
I learned this
The required value of the expression 5(z+4)+5(2-z) after simplification is given as 30.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Given expression,
= 5(z+4)+5(2-z)
Apply the distributive property,
= 5z + 20 + 10 - 5z
Adding the alike terms
= 5z - 5z + 20 + 10
= 30
Thus, the required simplified value of the given expression is given as 30 after simplification.

10n-7=-(-9n)-26
show work or explain, but please try to do it efficiently. thank you!!
Answer:
n = -19
Step-by-step explanation:
10n - 7 = -(-9n) - 26
Move all like terms to one side of the equation or the other.
-7 + 26 = -(-9n) - 10n
Combine all like terms.
19 = -(-9n) - 10n
Two minus signs = a positive
19 = 9n - 10
19 = -n
Divide by -1
-19 = n

Can someone please explain what an exponent is? Apparently, I was supposed to learn what it was in Fifth grade but I didn't learn it at my od school. My friend says you are supposed to multiply it by itself the number of times the exponent is, for example, 2² you would multiply it by two twice. My other friends say you add it the number of time the exponent is.
Answer:
5² for example an exponent is the small number and depending on the number it multipies itself however many times for example 5² would be 5 * 5 and 7² would be 7 * 7 and vise versa
Step-by-step explanation:
Answer:
Exponent- [tex]5^{2}[/tex]
An expression that represents repeated multiplication of the same factor is called a power. The number 5 is called the base, and the number 2 is called the exponent. The exponent corresponds to the number of times the base is used as a factor.

Please help braaaaaaaa
Answer:
1, yes it is a right angle. 2, yes it is a right angle.3, yes it is a right angle.
Step-by-step explanation:
1.Using the Pythagorean Theorem: 5 * 5 = 25, 12 * 12 = 144, 13 * 13 = 169, so 25 + 144 = 169 so yes it is a right angle.
2. Using the Pythagorean Theorem: 6 * 6 = 36, 8 * 8 = 64, 10 * 10 = 100, so 36 + 64 = 100, so yes it is a right angle.
3. Using the Pythagorean Theorem: 8 * 8 = 64, 15* 15 = 225, 17 * 17 = 289, so 64 + 225 = 289, so yes it is a right angle.
i need help i cant figure this out-
Answer:
106.73 pi
Step-by-step explanation:
540 is the area of everything because 3 * 18 is 540.
The formula for the area of a circle is pi*(r^2)
The top ball has a diameter of 6 so we divide that by 2 to get the radius, 3. We can plug that in to get pi*3^2
We can simplify that to pi * 9
The next ball has a diameter of 9. Divide by 2 to get the radius, 4.5.
Plug that in to get pi * (4.5^2) simplified to be pi *20.25
The last circle has a diameter of 12 so therefore it has a radius of 6.
Plug that in and you get pi*(6^2). Simply that to get pi * 36
To find the area of all the balls we just need to add them. We get 55.25 * pi.
To subtract it they need to be either not in pi or both in pi. I will make them both not pi.
65.25 * pi = 204.885
I used 3.14 as pie.
To find the shaded area we need to subtract 204.885 from 540. When we do that we get 335.12.
We need to divide by pi now to get in terms of pi.
335.12 / 3.14 = 106.726115
You can round this to 106.73 You can round to any digit you want.
