Answer:
Step-by-step explanation:
Equation
L = a + (n - 1)*d
Givens
L = 55
a = 13
n =8
Solution
55 = 13 + (8 - 1)*d Combine
55 = 13 + 7d Subtract 13 from both sides
55 - 13 = 7d
42 = 7d Divide by 7
d = 6
Answer:
x=76
Step-by-step explanation:
The two marked angles are alternate angles, which means they're equal.
34x+95=3(14x+9)
We move all terms to the left:
34x+95-(3(14x+9))=0
We calculate terms in parentheses: -(3(14x+9)), so:
3(14x+9)
We multiply parentheses
42x+27
Back to the equation:
-(42x+27)
We get rid of parentheses
34x-42x-27+95=0
We add all the numbers together, and all the variables
-8x+68=0
We move all terms containing x to the left, all other terms to the right
-8x=-68
x=-68/-8
x=8+1/2

Answer:
• Group the h terms by organised term arrangement :
• Then using distributive property, factorise out the value h so that the reverse is true.
• for the variable "lw", divide it by h in order to add it to the bracket of (w + l). Make sure the reverse is true:
• finally, completely factorise out the value h
