Answer:
C. 7 inches x 10.5 inches
Step-by-step explanation:
7 by 10.5
7/2 = 3.5
10.5/3 = 3.5
Therefore, they each have the same dilation.
So, your answer is C. 7 inches x 10.5 inches
Th equation is given as 2500 = 30x + 1900. Then the number of weeks he needs to reach his goal will be 20 weeks.
A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will beone.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Samuel has $1900 in the bank he wishes to increase his account to a total of $2500 by depositing $30 per week from his paycheck.
Let x be the number of weeks. Then the equation will be
2500 = 30x + 1900
Simplify the equation, then we have
30x + 1900 = 2500
30x = 2500 - 1900
30x = 600
x = 600 / 30
x = 20 week
The number of weeks he needs to reach his goal will be 20 weeks.

Answer:
The length of a side of the flag is 7.2inches
Step-by-step explanation:
Let length = x
Let hypotenuse = x+3
UsingPythagoras'Theorem:
x^2 + x^2 = (x+3)^2
x^2 + x^2 = x^2 + 6x + 9
2x^2 = x^2 + 6x + 9
×^2 - 6x - 9 = 0
x=[-(-6)+sqrt.(-6)^2-4(1)(-9)]/2(1)
×=[6+sqrt.72]/2
×=7.2inches
×=[-(-6)+sqrt.(-6)^2-4(1)(-9)]/2(1)
x=[6-sqrt.72]/2
×=-1.2(rej)
(PS.sqrt is square root)

Answer:
7.2 in
Step-by-step explanation:
Let length of side of flag=x
Hypotenuse of right triangle=x+3
According to question information
Using Pythagoras theorem
Using identity:
Using quadratic formula :
It is not possible because the length of side is always positive.
Hence, the side of flag=7.2 in
