Step-by-step explanation:
The perimer of a traingle is the saum of its sides
P = 2(3x+7) + 2(2x+2)
- P= 2(3x+7) + 2*(2x+2) multiply (3x+7) and (2x+2) by 2
- P= 6x+14+4x+4 add the khown values together
- P=6x+4x+18 add the terms with the variable x
- P= 10x+18
Answer:
length of unknown side is 59
Step-by-step explanation:
i) x (x+2)(3x)
ii) 3x^3+6x^2
iii) (x^2+2x) +(3x^2+6x) +(3x^2)
iv)7x^2+8x
Since the average is <numbers combined> over <number of numbers>, we have 4+1=5 numbers (tests) and 92+91+94+79+x=356+x, resulting in
(356+x)/5=90. Multiplying both sides by 5, we get 356+x=450 and by subtracting 356 from both sides we get x=94 as the minimum score
Hi, thank you for posting your question here at Brainly.
This is a common work problem in Algebra. To solve this, the general form of the equation would be:

let A denote you and B denote your classmate. Substituting,
