Answer:
x is 12
Step-by-step explanation:
You can find x two different ways.
The first way is to look at the numbers on the left side. You need to find the scale factor used to get from 4 to 6.
4 x 1.5 = 6
Use this for the 8
8 x 1.5 = 12
The other way you can use is look at the number on the top triangle. You need to find the scale factor used to get from 4 to 8.
4 x 2 = 8
Use this for the 6
6 x 2 = 12
Answer:
s = 4
Step-by-step explanation:
Note that the triangle has 2 congruent base angles, both 45°
This means the triangle is isosceles with congruent legs, then
s = 4
Answer:
D
Step-by-step explanation:
Paul can type 60 words per minute and Jennifer can type 80 words per minute. Paul typing speed / Jenifer typing speed = 60/80 = 3/4. Paul type 3/4 as fast as Jennifer. Log in for more information.
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
