Answer:
Step-by-step explanation:
x-30=14-3x
collect like terms: 4x=14+30
add numbers: 4x=44
divide both sides by 4
x=11
Multiply both numerator and denominator with 8+5i. Then you get
Point C, since pi=around 3.14
Hope that helps :)
Answer:
RP = 2.3
PQ = 1.0
RQ = 2.3
Step-by-step explanation:
The pictures says RP = RQ,
so:
3x - 0.4 = x + 1.4
this you can simplify to:
x = 0.9
Then fill x in:
RP = 3*0.9 - 0.4 = 2.3
PQ = 0.9 + 0.1 = 1.0
RQ = 2.3
Answer:
864 ft^2
Step-by-step explanation:
Surface area equation is the same as the one used in the other problem; S=(1/2)lP + B
one side is 20 x 14 = 280
another side is 12x14 = 168
another side is 16x14 = 224
the triangle bases are A=(1/2)bh
(1/2)12 x 16 = 96
2(96) = 192
Add all sides together 192 + 224 + 280 + 168 = 864
