Answer:
11x=1
Step-by-step explanation:
15x+4=5+3x+1x Bring everything with an x in front of it to the left side
15x-3x-1x+4=5 Simplify the x values
11x+4=5 Bring the 4 to the right side
11x=5-4
11x=1
Answer:
7()=11
8()=42
I could barely see the answer for number 9 sorry :(
Step-by-step explanation:
the 7() is 2(3)+5
2(3)=6
6+5=11
Question (8)
c^2+3a x b
c(6)^2+ 3(3) x 2/3
36+9 x 2/3
36+6=42
Answer:
see explanation
Step-by-step explanation:
Since the 2 figures are similar then the ratios of corresponding sides are equal, that is
=
( cross- multiply )
18x = 48 ( divide both sides by 18 )
x =
=
= 2 
Similarly
=
( cross- multiply )
18y = 30 ( divide both sides by 18 )
y =
=
= 1 
Candy draws a square design with a side length of x inches for the window at the pet shop. She takes the design to the printer and asks for a sign that has an area of 16x2 – 40x + 25 square inches. What is the side length, in inches, of the pet shop sign?
Answer:
the length of the sign is
inches
Step-by-step explanation:
Given
Area of the square of design = 
First we find the roots of equation 
The roots of the quadratic equation
are given by

where 






That is, the factors of the polynomial
are
and
.
So, Area of the square design =
= 
Area of a square = Length^2
Thus, the length of the sign is
inches
There are two terms which is (w,x)
