Answer:
DEC+DEF=180
DEC=180-116
DEC=64°
in triangle DCE
angle D+angle C+angle E=180
7y+6+4y+64=180
11y+70=180
11y=180-70
11y=110
y=110/11
y=10°
angle C=4y
=4(10)
=40°
Step 1,
what i am thinking you're saying is 2x-1/4(12x+4)
so you would distribute the -1/4 to the 12x and the 4.
therefore making it a negative, not a positive.
so, i think step 1 is wrong.
Answer:
3/2 3*5=15
3/2=1.5
Step-by-step explanation:
Step-by-step explanation:
p⁴+8p²q²+16q⁴
(p²)²+2×p²×4q²+(4q²)²
We know that,
Therefore,
- (p²)²+2×p²×4q²+(4q²)²
- (p²+4q²)²
- (p²+4q²)(p²+4q²)
Answer:
25
Step-by-step explanation:
you would do the total which is 45-20
