Answer:
(2x-5)feet
Step-by-step explanation:
The area of the rectangular garden A = Length × Width
Given the area A(x) = 2x² - 21x + 40
And the width =x-8 feet
To get the length, we will simply factorise the area function as shown;
You will just factorise the area
Factorizing 2x² - 21x+40
2x² − 21x + 40
2x² -16x - 5x + 40
2x(x - 8) -5(x - 8)
=(2x−5)(x−8)
Hence the length of the garden is
(2x-5)feet
Answer:
0.31 - 0.39
Step-by-step explanation:
3/10 = 0.3
2/5 = 0.4
All the values between 0.3 and 0.4 excluding 0.3 and 0.4 (can't be 0.3 or 0.4)
Hello from MrBillDoesMath!
Answer:
x = 31
Discussion:
angle A + angle C + angle B = 180 (180 degrees in a triangle)
angle A + 57 + 61 = 180 => (substitution)
angle A + 118 = 180 =>
angle A = 180 -118 = 62
By the congruence statement, angle A = angle D = 2x so
62 = 2x =>
x = 31
Thank you,
MrB
It would be 70% of 400
490(.7) = 280
45 degrees
Right triangle = 180
90 degrees is given
180-90= 90
Then divide by 2
90/2= 45 degrees
