The first expression can be simplified by combining like terms.
First, the terms "4b" and "-3b" can be combined to form "b"
Then, the terms "-7" and "9" can be combined to form "2"
Finally, we simply put these two final terms together, to form "b+2"
Hence, 4b-7-3b+9 is equal to be + 2.
Hope this helps!
I’m pretty sure it is the first one
F(0)=4-8x
f(0)=4-8(0)
f(0)=4
Answer:
11.7 m²
Step-by-step explanation:
What is the area of each triangle ?
A = b×h/2
= 5.2m×4.5m/2
= 23.4m²/2
= 11.7 m²
The answer to this question is <span>B. (sqrt 2, 315 degrees). This polar coordinate is the only coordinate with its angle in quadrant 4 and a length of √1^2 + (-1)^2 = √2.</span>
