Answer:
140+5x^2
If x =3
140+5(3^2)
3^1=3
3^2=9
So,
140+5(3^2) = 140+5(9)
= 140 +45
= 195
Step-by-step explanation:
y=5x+2
4x−y=0

The expression 2(l + w) is used to calculate the perimeter of a rectangle, where l is length and w is width. If the length is Fraction 2 over 3 unit and the width is Fraction 1 over 3 unit, what is the perimeter of the rectangle in units? (3 points)
Answer:
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
2[2\3±1\3]
2×2\3=4\3
2×1\3=2\3
4\3±2\3=6\3
6\3 is the same as 2 because if you divide 6 by 2 you will get 2
so the answer is 2

Δ ABC is a right triangle at ∠ B
Using Pythagoras' identity in the right triangle
x² + 7² = 18²
x² + 49 = 324 ( subtract 49 from both sides )
x² = 275 ( take the square root of both sides )
x = [tex]\sqrt{275}[/tex] ≈ 16.6 ( to the nearest tenth )

A countertop is 11 feet long and 4 fee t wide.
What is the area of the countertop in square meters? Use the conversion 1 foot = 0.305 meter. Round your
final answer to 2 decimal place
Answer:
4.09m^2
Step-by-step explanation:
A countertop is 11 feet long and 4 fee t wide.
Using the conversion
1foot = 0.305 meter
11fet = 11(0.305)
11feet = 3.355 m
4 feet= 4 * 0.305
4feet = 1.22m
Area of the countertop = Length * Width
Area of the countertop = 3.355 * 1.22
Area of the countertop = 4.0931m^2
Hence the required area is 4.09m^2 to 2 decimal places
the diameter of a circle is 8 ft. Find the circumferenceto the nearest tenth.
Answer:

So essentially, apply to your calculator:
2(3.14)4=25.12
pretty simple! hope this helps!
