Answer:
The answer is below
Step-by-step explanation:
A rectangle has an area of x² + 7x + 12. Use factoring to find possible dimensions of the rectangle. Explain why you can use factoring to find the answer.
Solution:
A rectangle is a quadrilateral (ha four sides and four angles) in which opposite sides are parallel and equal to each other. All the four angles in a rectangle are 90° each.
The area of a rectangle is given by:
Area = length * width
Hence the area is the product of two sides.
Given that:
Area = x² + 7x + 12
Factoring to find both the length and width of the rectangle:
Area = x² + 7x + 12
Area = x² + 4x + 3x + 12
Area = x(x + 4) + 3(x + 4)
Area = (x + 4)(x + 3)
After factoring we can see that the area is the product of (x + 4) and (x + 3). Hence x + 4 is the length and x + 3 is the width.
Answer:
130 degrees
Step-by-step explanation:
We know (x-10)+(2x+10) is 180 degrees.
So first we need to find x. (x-10)+(2x+10)=3x
3x=180
x=60
Angle TRV is 2x+10.
If we input 60 in the place of x, it is 2(60)+10=120+10=130.
The answer is 130 degrees.
18s is divided by 3. And 25t is divided by 5
Answer:
Ummmm my answer was deleted and idk why so im just gonna repost what i said cause i think it was a bug or smth. Answer is 3h
Step-by-step explanation:
Together Clare and Kiran are walking to each other at 8mph so you do 24 divided by 8 and get three so three hours
Option 1 : -22
using formula
(a + b )(a - b ) = a^2 - b^2
(√10 + 2√8) (√10 - 2√8)
= (√10)^2 - (2√8)^2
= 10 - 2×2×8=10-32
= -22
2nd question answer is option 3
