Answer:
-1.61481
Step-by-step explanation:
-1.4x = 4(x + 2.18)
Pemdas
get rid of parentheses
-1.4x= 4x +8.72
then subtract from both sides to get x's on the same side
-1.4x-4x=4x+8.72-4x
positive 4x and negative 4x cancel each other out and put the x['s on the left side together so -5.4x
-5.4x=8.72
divide -5.4 from both
-5.4x/-5.4= 8.72/-5.4
x=-1.61481 or round up to two

Answer:
c
Step-by-step explanation:
If the dot product of the vectors is zero then they are perpendicular
(5, - 1) • (- 3, 6)
= (5 × - 3) + (- 1 × 6) = - 15 + (- 6) = - 15 - 6 = - 21 ≠ 0
Since product is not zero vectors are not perpendicular

Answer:
Area is 70ft
Step-by-step explanation:
Area of a triangle is A=b × h/ 2 or A=1/2×bh
Let height equal h & base equal b
So,
h=14
b=10
Solve,
A=1/2×14×10
A=1/2×140
A=70
Therefore, the area is 70 feet
Answer:
x=52
Step-by-step explanation:
r=90 s=34 q=180-(90+34)
180-(90+34)=56
to find angle sqr
180-56=124
124=x+72
52=x
