the answer is D 9.2 units
Answer:
5x²+7x-4
Step-by-step explanation:
Given: (7x²+2x-1)-(2x²-5x+3)
Distribute: 7x²+2x-1-2x²+5x-3
Rearrange: 7x²-2x²+5x+2x-3-1
Combine like terms: 5x²+7x-4
Your final answer is thus 5x²+7x-4

Answer:
<FGH and <JKL are supplementary
<AED and <BEC are complementary
Step-by-step explanation:
For supplementary angles, the sum of the pair of angles must be 180degrees
Given;
<FGH = 109degrees
<JKL = 71degrees
Taking the sum
<FGH + <JKL
= 109 + 71
= 180
Since the sum of the angles is 180, hence <FGH and <JKL are supplementary
Similarly;
Given
<AED = 45degrees
<BEC = 45degrees
Taking the sum
<AED + <BEC
= 45 + 45
=90degrees
Since the sum of complementary angles is 90degrees, hence <AED and <BEC are complementary
