Answer:
-4x^2+5x-28
Step-by-step explanation:
Expand -7(x^2 +4) = 3x^2+5x-7x^2-28
Simplify 3x^2+5x-7x^2-28 = -4x^2+5x-28
Answer:
y=-2
Step-by-step explanation:
in other words, the question is asking
"six time what plus four equals 12?"
we know that 6 ⋅ 2 = 12
therefore if we plug the -2 into the Y we get
6(-2+4)=12
6(2)=12 or 6⋅2=12
therefore the answer is y=-2
Answer: y = 2x + 12
Explanation: The slope-intercept form is y = mx + b, where m is slope and b is the y-intercept. Substituting 2 for m, 6 for x, and 24 for y, we have 24 = 2(6) + b. Simplifying, we get that b = 12, so the equation is y = 2x + 12.
The first one would be 90%. the second one would be 2.3%. the third one would be 150%. and the final one will be 83.3333%.
LA = (2l + 2w)h
Plug in what we know:
LA = (2(11) + 2(7))(4)
Multiply:
LA = (22 + 14)(4)
Add:
LA = 36(4)
Multiply:
LA = 144
