Step-by-step explanation:
Formula of a trapezoid:
B1(base 1) + B2(base 2) x H (Height) x 1/2 (basically dividing by 2)
Answer:
3 and 5/8
Step-by-step explanation:
1 1/2 + 2 1/8 = 29/8
Simplify to 3 5/8
Answer:
x= 11.4
Step-by-step explanation:
for the base of the triangles BC is 15 and DF is 5 so if 5 times 3 is 15 then you are reducing the other triangle to a third of the big triangles size. so 3.8 times three is 11 4
Answer: -10x+7
Step-by-step explanation: hope this helps!
Answer:
5
Step-by-step explanation:
f(-4) = sqrt(2(4)^2 -7) (Plug in -4)
f(-4)= sqrt(2(16)-7) (Square 4 which is 16)
f(-4)=sqrt(32-7) (Multiply by 2)
f(-4)=sqrt(25) (Subtract 7)
f(-4)=+/- 5 (take the square root of 25 which is postive/negative 5)
Since this is a function there can only be one y to an x the positive 5 is the only answer
