to solve for the dimensions (x+7)(x+2)=66,
we can first use the foiling method to simplify the left side.
x^2 + 2x + 7x + 14 = 66
x^2 + 9x + 14 = 66
now, subtract 66 from both sides.
x^2 + 9x - 52 = 0
now, split this into two parentheses.
(x + 13)(x - 4)
since the root of -13 would give you negative values, x=4. This means that the dimensions of the rectangle are 11 and 6.
Answer:
2=p
Step-by-step explanation:
-5p+7=5p-13
+5p +5p
7=10p-13
+13 +13
20=10p
÷10 ÷10
2=p
Answer:
<em>x = y = 64° , z = 20°</em>
Step-by-step explanation:
<em>x = y</em> = 
<em>= 64 </em>°
m∠ADC = 52° + x
m∠ADC = 52° + 64° = 116°
<em>z</em> = 180° - 116° - 44° <em>= 20</em> °
