Answer:
9
Step-by-step explanation:
3/7 multiplied by 21 = 3/7 x 21 = 9 = 3/7 x 21/1 = 63/7 = 9
Or if you can't do the math - Think of a pizza with 21 slices . Now cut this pizza into 7 equal parts. You will find that each part contains exactly 3 slices. Now, eat 3 of these parts. With three slices in each part, you ate 9 slices - which is three sevenths of 21.
X^2-3x = x(x-3)
x^2-9 = x^2 - 3^2 = (x-3)(x+3)
HCF = x-3
B "it's" means (it is) and that would not make sense if it fell on it is side .
Answer:
The answer to your question is 757.1 cm²
Step-by-step explanation:
Data
Ratio 1: 1.618
long side = 35 cm
Area = ?
Process
1.- Use proportions to solve this problem
1 : 1.618 :: x : 35
x = (35 x 1) / 1.618
x = 35 / 1.618
x = 21.63
2.- Calculate the area of the rectangle
Area = base x height
Area = 35 x 21.63
Area = 757.1 cm²
Answer:
Step-by-step explanation:
According to the following pattern sequence (
), it is <u>Arithmetic Sequence</u>, because every negative number is subtracted by 
. So, to find the <u>24th term</u>, you need to use the <u>Arithmetic Sequence Formula</u> and solve to find the 24th term:
: nth term in the sequence
: 1st term
: term position
: Common difference
-Apply to the formula:
-Solve:
Therefore, the 24th term is 
.
