Answer:
21 to 28
Step-by-step explanation:
Reduce each ratio to lowest terms by dividing by any common factors. (It helps to know your multiplication tables, or a quick way to find the greatest common divisor.)
15 : 20 = (5*3) : (5*4) = 3 : 4
_____
21 : 28 = (7*3) : (7*4) = 3 : 4 . . . . same as 15 : 20
5 : 10 = (5*1) : (5*2) = 1 : 2 . . . . . ≠ 3:4
18 : 25 . . . has no common factors . . . ≠ 3:4
I’m assuming 9? There isn’t a question so
Answer:
BAE
Step-by-step explanation:
A quarter circle (angle BAD) will have a measure of 360°/4 = 90°. An angle of 105° will be larger than 1/4 circle. The only angle on the diagram larger than BAD is BAE.
The measure of angle BAE is 105°.
24 = 2³ × 3
64 = 2³ × 2³
88 = 2³ × 11
So, the common factors are : 1, 2 , 4, 8
Step-by-step explanation:
the area of the square is (x+2)^2 and the factored form of it is x^2+4x+4
since we know the area is = 7 therefore
x^2 + 4x +4 = 7 and x^2 + 4x = 3
if you want to find the value of x :
x^2+4x+4 = 7
x^2+4x -3 = 0
(x-3)(x-1)=0
x = 3 or
x = 1
