The area of this shape is 12.
Area of a triangle = 1/2 x bh
b= base
h = height
So,
1/2 (6)(4)=12
Hope this helps!
Answer:
Divide both sides by 3.
(x+2)^2=16
Square root both sides.
x+2= ± 4 (plus OR minus, can be either so we have to include both)
Minus 2 from both sides.
x=-2 ± 4
Add and minus the 4 to -2.
x = -2-4 = -6 and x=-2+4 = 2
Answer:
angle A=68°
angle B=68°
angle D= 111°
Step-by-step explanation:
angle D = angle C
angle D = 111°
interior angle of a quadrilateral=360°
angles A and B are equal . represent them by a°
a°+a°+111°+111°=360°
2a°+222°=360°
2a°=360°-222°
2a°=138°
2a°/2=138°/2
a°=68°
therefore angle A=68° and angle B =68°
Answer:
y = x² + 10x + 74
Step-by-step explanation:
Given
y = (x + 5)² + 49 ← expand the factor using FOIL
= x² + 10x + 25 + 49
= x² + 10x + 74 ← in standard form
