The length of each side of the larger square is 8 cm.
<u>Step-by-step explanation</u>:
Step 1 ;
- The combined area of two squares = 80 sq.cm
- The side of small square = x
- The side of larger square = 2x
Step 2 :
Area of the square = a^2
Area of small square + area of large square = 80
x^2 + (2x)^2 = 80
x^2 + 4x^2 = 80
5x^2 = 80
x^2 = 80/5
x^2 = 16
x = ±4
Step 3 :
Since length cannot be negative, the value of x= 4
∴ The length of the side of small square = 4cm
The length of the side of larger square = 2x = 8cm
Answer:
x times y
Step-by-step explanation:
k is the value of x times y
Answer:
D
Step-by-step explanation:
use the formula for point slope form, since all of your choices are in that form : y-y1=m(x-x1) (m is the slope)
we're given that m=2 and the point is (2,9)
Substitute into the equation
y-9=2(x-2)
That means that the answer is D
Hope this helps!
Law of cosines:
a^2 = b^2 + c^2 -2 *b*c*coa(a)
a^2 = 60.5^2 + 257^2 - 2*60.5*257*cos(31)
a^2 = 3660.25 + 66049 - 2 *60.5 * 257 * 0.857167
a^2 = 3660.25 + 66049 - 26655.33
a^2 = 43053.92
a = SQRT(43053.92)
a = 207.49 = 207.5 feet.
The answer is A.
To solve problem #1 follow the steps below...
Step 1:Think back to PEMDAS
P=Parentheses
E=Exponents
M=Multiplication
D=Division
A=Addition
S=Subtraction
(Think of M,D as brothers and whichever once comes first in the problem you do.This rule also applies to A,S)
Step 2: Look back to your problem
(6 divided by 2 plus 1) plus 10x2
Step 3: Start with the parentheses
6 divided by 2 plus 1
Step 4: Do the division first
6 divided by 2=3
Step 5:Now the addition
3 plus 1=4
Step 6: Rewrite the problem
4 plus 10x2
Step 7: Do the multiplication
10x2=20
Step 8: Rewrite your problem again
4 plus 20
Step 9: Solve
4 plus 20=24
Step 10: Look back at your work and see what order your operations were done in
.Division
.Addition
.Multiplication
.Addition
Step 11: Compare your order to the choices
