Answer:
length = 20cm
breadth = 8cm
Step-by-step explanation:
solution;
length(l) = x + 12
breadth(b) = x
perimeter (p) = 56 cm
we know that,
perimeter(p) = 2(l + b)
or, 56 = 2(x + 12 + x)
or, 56 = 2(2x + 12)
or, 56 = 4x +24
or, 56 - 24 = 4x
or, 32 = 4x
or, 32 / 4 = x
x = 8
now
putting the value of x in length and breadth
length = x+ 12
=8 + 12
=20cm
breadth = 8cm
Answer:
the answer is 34.
Step-by-step explanation:
the Phythagorean theorem is a^2 + b^2 = c^2.
I hope this helped and if it did I would appreciate it if you marked me Brainliest. thank you and have a nice day!
D. take the number of dollars she has and multiply by .25.
dividing by a number is the same as multiplying by it's reciprocal. since she is dividing by .25, she needs to multiply by the reciprocal (4,) but instead, she is just multiplying by .25.
65 miles per hour
feet in a mile: 5,280 ft
65 divided by 60= 1.08 miles per minute
22 x 1.08 = 23.76 miles
23.76 mi x 5,280 ft = 125,452.8 ft in 22 minutes
Answer:
BC ≈ 14 units
Step-by-step explanation:
using Pythagoras' identity in the right triangle.
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
BC² + AB² = AC²
BC² + 18² = 23²
BC² + 324 = 529 ( subtract 324 from both sides )
BC² = 205 ( take square root of both sides )
BC = 
= 14.317.. ≈ 14 units ( to the nearest unit )
