<h3> length </h3>
a + b = 18cm
a = 18 - b
<h3> Area </h3>
a² + b² = 212cm²
(18-b)² + b² = 212
324 - 36b + b² + b² = 212
2b² - 36b + 112 = 0
b² - 18b + 56 = 0
b² - 4b - 14b + 56 = 0
b(b-4) -14(b - 4) = 0
(b-4) (b-14) = 0
b-4 = 0 OR. b-14 = 0
b = 4 cm b = 14 cm
so 4cm < 14cm
so , length of a side of the smaller square is 4cm .......
And , large square's = 14cm .....
Answer:
square one sides = 14, 14
square 2 sides = 4, 4
14 + 4 = 18
14 x 14 + 4 x 4 = 212
Step-by-step explanation:
14 x 14 + 4 x 4
this is the area of the 2 being added
the sides lengths are 14 and 4

Answer:
x=9, y=3
Step-by-step explanation:
-4x+6y=-18
y=-2x+21
-4x+6(-2x+21)=-18
-4x-12x+126=-18
144=16x
x=9
y=-2x+21
y=-18+21
y=3
Answer:
1000 : 1000 : 1500
Step-by-step explanation:
2 + 2 + 3 = 7
3500 ÷ 7 = 500
2 × 500 = 1000
2 × 500 = 1000
3 × 500 = 1500
1000 : 1000 : 1500
Answer:
0.5amps
Step-by-step explanation:
I is inversely proportional to resistance
I = k/R
k = I/ R
k = 20/5
k = 4
This means that, I = 4/R
So, when R = 8ohms,
I = 4/8
=0.5amps
Answer:
Step-by-step explanation:
Given
cups
ounce
Required
Number of ounces per cup (n)
To do this, we simply divide the Recipe by the call
So, we have:
Express as improper fraction
Rewrite as:
So basically what you wanna do is multiply across giving you 40/88 which you can simplify down to 5/11
Hope this helps :D
