X² - 169 = 0
x = ?
<span> Add 169 to both sides.
</span>
x² <span>− 169 + 169 </span>= <span>0 + 169</span>x² = 169
Square root
x = <span>± <span>√<span>169
</span></span></span>
<span><span>x = <span><span>13<span> or </span></span>x </span></span>= <span>−13
x can be 13 or -13.</span></span>
Answer:
that expression is not factorable with rational numbers
Step-by-step explanation:
Answer:
The zeros are the points on the x-axis where the graph intersects.
For factorization, you do (x - the zero) for each zero, and multiply them together.
7. A. The zeros are -2 and 4.
The factorization is (x + 2)(x - 4)
7 B. The zeros are 1 and 3.
The factorization is (x - 1)(x - 3)
Step-by-step explanation:
Answer:
The factory made 3 batches of granola bars.
Step-by-step explanation:
Given that:
1/6 barrel of raisins is used in each batch of granola bars.
1/6 barrel = 1 batch
1/2 barrel = x batches
As the relationship is proportional,
1/6 : 1 :: 1/2 : x
Product of mean = Product of extreme
Multiplying both sides by 6
Hence,
The factory made 3 batches of granola bars.
