Two the smaller right angled triangles are similar. Therefore:
Answer: a) 4.5
Pick out the like terms. 6x^2 (which equals 36x), 11x, 2x^2 (which equals 4x), -17x.
36+11+4= 51, -17= 34x
-3+-4= -7
The simplified expression would be 34x+-7.
(This could be wrong though, I'm sorry if it is ^^)
16 × (14 - 6) × 3 - 6^2 ÷ 6
parenthesis first
16 × (8) × 3 - 6^2 ÷ 6
exponents next
16 × (8) × 3 - 36 ÷ 6
multiplication and division from left to right
128 *3 -36 ÷ 6
384 -36 ÷ 6
384 -6
378
2 combines = 320 acres
320/2 = 160 acres per combine
160 * 6 = 960
Answer: 960 acres
Hope this helps!
Answer:
28
Step-by-step explanation:
The area of a trapezoid is found by
A = 1/2 (b1+b2) *h
where b1 and b2 are the bases and h is the height
The bases are 6 and 8 and the height is 4
A = 1/2 (6+8) * 4
A = 1/2 (14)*4
=28
