Hi there!
h(x) = 5x + 11
To find h(7) - 3, we can substitute 7 for x and subtract 3:
h(7) = 5(7) + 11 - 3
Simplify:
h(7) = 35 + 11 - 3
h(7) = 43

Answer:
Step-by-step explanation:
1) Split the second term in into two terms.
1 - Multiply the coefficient of the first term by the constant term.
2 - Ask: Which two numbers add up to 2 and multiply to -35?
7 and -5.
3 - Split 2x as the sum of 7x and -5x.
2) Factor out common terms in the first two terms, then in the last two terms.
3) Factor out the common term x+1.
4) Solve for x.
1 - Ask: When will (x+1)(7x-5) equal zero?
When x + 1 0 or 7x-5=0
2 - Solve each of the 2 equations above.
Answer:
Step-by-step explanation:
It is given that A 14 foot ladder is leaning against a building. The ladder makes a 45 degree angle with the building, then let AC=14 foot and ∠C=45°and AB be the length of the building.
Thus, using the trigonometry, we have
Substituting the given values, we get
⇒
⇒
⇒
⇒
Thus, the length of the building will be .
