Let h represent Kate's height at birth. Then: 142 cm = 3h - 2 cm.
Combining like terms: 144 cm = 3h, and h = 48 cm.
Kate's height at birth was 48 cm.
Answer:
Length = 12
Width = 8
Height = 4
Step-by-step explanation:
Let length of box = l
Width = 2/3 * l
Height = 1/3 * l
Volume of the box = 384 ft³
Volume = Length * width * height
Volume of box = l * 2/3 l * 1/3 l
384 = 2l³ / 9
384 * 9 = 2l³
3456 = 2l³
l³ = 3456 / 2
l³ = 1728
Take the Cube root of 1728
l = 12
Length = 12
Width = 2/3 * 12 = 8
Height = 1/3 * 12 = 4
Answer:
Because the Length is 5 times the width, L(length) = 5w. You can use this information to update your perimeter.
P= L + W
P= 5w + w = 6w
P = 120, 120= 6w
120/6 = 6w/6
20 = w
L = 5w, L = 5(20) = 100
A = L x W, 100 x 20 = 2000
This means 2000 is the area
Answer:
-11
Step-by-step explanation:
Firstly simplify your expression...by dealing with the brackets
; -k - 7k + 6n + 3n
;then substitute with the given values into your expression,
;-(-2) -7(-2) + 6(-3) + 3(-3)
; 2 + 14 - 18 - 9
; 16 - 27
;Hence the answer is -11
