120/2=60 (sum of both lengths)
4x+4=60
4x=56
x=14
length=46
width=14
Answer:
Step-by-step explanation:
2x(x - 3) + 7(x - 3)
2x^2 - 6x + 7x - 21
reduce
2x^2 + x - 21
if this is equal to 0 then:
2x^2 + x - 21 = 0
factored:
(2x + 7)(x - 3) = 0
How that was done:
Divide the (2x^2) into (2x) and (x).
Divide the (-21) into (+7) and (-3). You choose these numbers so that their sum, when multiplied by (2x) and (-3), adds up to (+x).
Answer C. base side length = 30.6 cm, height = 27.3 cm
Get the equation to slope-intercept form: y = mx + b
6x + 3y = 6
Subtract 6x from both sides. This will give you 3y = -6x + 6.
Then, divide by 3 on both sides. This gives you y = -6x + 2.
2 is your y intercept and -6 is your slope.
Area of the figure = 27 square units
Solution:
Number of full squares shaded = 24
Number of half squares shaded = 0
Number of more than half square shaded = 3
Number of less than half square shaded = 4
Area of the figure = Number of full square + Number of more than half square
+ Half of number of half squares
= 24 + 3
= 27 square units.
Area of the figure = 27 square units
