Anastasy [175]

Answer:

Step-by-step explanation:

Since he wants to have equal number of rows and columns..the number of plants must be a root number. 6203 is not a root number. 6241 is the closest root number

(√6241= 79)

So he needs a minimum of 6241 plants in total for it.

6241-6203= 38

Therefore he needs 38 more plants

3) Let h(x)= |2x|-4. Find h(x) when x = -7.<br> a) -10<br> b) 10<br> c) -13<br> d) 13

svlad2 [7]

Answer:

$h(x) = 10$

Step-by-step explanation:

Given

$h(x) = |2x| - 4$

$x = -7$

Find h(x)

Substitute -7 for x

$h(x) = |2*-7| - 4$

$h(x) = |-14| - 4$

Absolute values return positive. So:

$h(x) = 14 - 4$

$h(x) = 10$
