Answer:
Same length
24 ÷ 2=12
There is 12 inches in a foot
1 + 1= 2 ft
24 inches = 2 feet
Answer:
1)
A)
We must use the formula b x h/2 12 x 8/2 = 48
A=48
B)
We must use the formula 1/2a root c squared - a squared
Solving and substituing will get you 35.78
2)
A)
We must divide 81 by 2 to get 9. Since this is a square, all sides will be 9. Then, we must add 9 four times to get 36 cm as our perimeter
B) If we draw the square with a diagonal line, we can understand that the diagonal line (hypotenus) is s root 2.
3) The formula for this area of a triangle is h x b/2. We must substitute the numbers to get our answer:
h x b /2 = 10 x 20/2 = 200/2 = 100
AREA IS 100cm squared

Answer:
Step-by-step explanation:
The answer is B.
Use the sum-product pattern
2+3−3−9
Common factor from the two pairs
2+3−3−9x2+3x−3x−9
(+3)−3(+3)
Rewrite in factored form
(+3)−3(+3)
Solution:
(−3)(+3)

Answer:
(a) 3 - 2x - 2x² (b) -21
Step-by-step explanation:
given, y +2x² = 3 -2x
make y the subject:
y = 3 - 2x - 2x²
if y = f(x)
then
f(x) = 3 - 2x - 2x²
(b)<u> to find f(3) we need to replace x with 3:</u>
<u />
3 - 2(3) - 2*(3)²
-21
V=(1/3)(area of the base)(<span>altitude)
V=</span><span>(1/3)(</span>6²)(6)= 72 m³
