Answer:
length and width of the photo are: w = 6cm l = 8cm
Step-by-step explanation:
Area = 168cm^2
Area = w • l
168 = (x + 3 + 3) • (x + 2 + 3 + 3)
168 = (x + 6) • (x + 8)
expand
168 = x^2 + 14x + 48
subtract 168 from both sides
0 = x^2 + 14x - 120
simplify
0 = (x - 6) • (x + 20)
x = 6 or -20
since we are dealing with a measurement of a physical object x > 0
x = 6cm
w = x = 6cm
l = x+2 = 8cm
Answer:
y = x² + 3x
Step-by-step explanation:
y = (x * x) + (3 * x)
y = x² + 3
Answer:
<h3>X=-1/8=-0.125</h3>
Step-by-step explanation:
Isolate x on one side of the equation.
x+2/4=3/8
2/4=1/2 (First, use the common factor of 2.)
x+1/2=3/8
x+1/2-1/2=3/8-1/2 (Then, subtract 1/2 from both sides.)
3/8-1/2 (Solve.)
3/8-1/2=-1/8
-1/8=-0.125
x=-1/8=-0.125
In conclusion, the final answer is x=-1/8=-0.125.
